Hub-and-spoke topologies save on tunnel capacity since tunnels are only built to the hub routers. You can use more zones even if you only have one network interface. Specifies the A basic ACL can filter packets based on source IP addresses; an advanced ACL can filter packets based on both source and destination IP addresses. allowing extension of Layer 2 domains across sites. In Cisco IOS XE Release 3.15S and later releases, zone-mismatch drop is configured in the class parameter map. Starting from Cisco Multi-Site Orchestrator Release 2.2(1), inter-version support has been introduced to allow MSO to manage APIC domains running different ACI software releases (Figure 27). An IP address subnet mask must have continuous 0s and 1s, whereas a wildcard mask can have discontinuous 0s and 1s. deployed in a separate site and reachable via that remote L3Out connection (both intra-VRF and inter-VRF). Sites which cannot connect directly should be set up to reach each other through the data center or other centralized site. Additionally, there is an option to use the bootstrap method, which applies to IOS XE SD-WAN routers only, where there is a configuration loaded via bootflash or a USB key in order to get the device onto the SD-WAN network which can be used when requirements for automated provisioning are not met. As a general rule, each vManage server supports approximately 2000 devices, and up to 6 servers have been tested in a single cluster. even when managing Cisco ACI fabrics that span the world. To see which zones are available on your system: The firewall-cmd --get-zones command displays all zones that are available on the system, but it does not show any details for particular zones. vManage and WAN Edge routers act as clients when connecting to vSmart controllers, so when using TLS, their source ports are random TCP ports > 1024. There may be branches that require features or connectivity that are not yet fully supported by a pure SD-WAN deployment with IOS XE SD-WAN or vEdge routers. nftables: Use the nftables utility to set up complex and performance critical firewalls, such as for a whole network. When a new rule is added to the ACL, the system allocates ID 15 to this new rule (15 is greater than 12 and is the minimum multiple of 5). The following describes how to configure security policies in typical VPN scenarios. This prevents attempts to establish BFD sessions to TLOCs with different color. Figure 126 shows, in contrast, a scenario where the multicast source is connected to the external Layer 3 network, and the receivers are deployed inside the Cisco ACI fabrics. Controlling traffic with predefined services using CLI, 47.3.3. To provide even more flexibility when organizing policy objects, Cisco Multi-Site Orchestrator Release 2.2(1) also began supporting the migration of EPGs and BDs across templates (in the same schema or even across schemas) that are associated to the same tenant. The ZTP or PnP process cannot succeed without this. Configuring ethtool offload features", Expand section "36. The L3Out objects defined in each APIC domain are exposed to the Cisco Multi-Site Orchestrator to be associated to External-EPGs that can be defined directly on the MSO, as explained later in this section. The preferred group construct is enabled at the VRF level and allows grouping together of all (or a subset of) the EPGs defined in that VRF. All of the devices used in this document started with a cleared (default) configuration. The first requirement before intrasubnet IP communication across sites can be achieved is to complete the ARP exchange between source and destination endpoints. You will not be able to see any open ports that have been opened as a service. Verify Behavior. protocol In the specific example shown above, when a source connected to an ACI leaf node in site 1 generates a multicast stream, the FHR device generates a PIM Data Register message and forwards it to one of the BL nodes available in the local site. Page 230 Select the Firewall system tab. You can control which transport is used with the vmanage-connection-preference
command under the tunnel interface on a WAN Edge. (highly recommended) Upgrade and activate half of the vBond orchestrators and let them run stable for a time (24 hours for example) before upgrading and activating the other half. Traffic flows freely between interfaces E0 and E1 because they Getting connectivity to the Service Provider gateway in the transport network usually involves configuring a static default gateway (most common), or by configuring a dynamic routing protocol, such as BGP or OSPF. When deploying Multi-Pod and Multi-Site together, the same IEVPN-RID address can be used to establish EVPN adjacencies between spines of different pods (part of the same fabrics) and spines of different sites (part of different fabrics). The WAN Edge routers securely communicate to other WAN Edge routers using IPsec tunnels over each transport. However, 3.1(1) is the last supported MSO release with this specific deployment option. At this point, the traffic will reach the external multicast receiver H3, either following a direct path or via the RP, depending on whether the Shortest-Path Tree (SPT) switchover has happened or not. A different set of GIPo addresses are reserved for the VRFs when compared to the GIPo addresses associated to the bridge domains (and used to forward BUM traffic inside the fabric). zone-name. Note: As of Release 3.4(1) of the Orchestrator service, the capability of migrating objects across templates is restricted to BDs and EPGs, and only if the templates are associated to the same tenant. The opposite operation is also possible, when BD/EPG pairs that are stretched must be removed from a remote site and become instead site-local objects. To manage your router, use the web interface, or download the maintenance utilities. Configuring network teaming", Collapse section "7. Also, the recommendation is to deploy the MSO application on CASE starting from Cisco Application Services Engine Release 1.1.3, which also requires a minimum Cisco Multi-Site Orchestrator Release 3.0(2). This has two consequences: The information about the L3VNI value for the L3Out in site 1 must be propagated from site 1 to site 2 via the MP-BGP VPNv4 control plane. Enabling traffic forwarding between different interfaces or sources within a firewalld zone", Expand section "47.15. Policies pushed to a site from Cisco Multi-Site Orchestrator can be modified locally in the APIC. In this case, routing updates sent to the WAN can be properly tuned to help ensure that all incoming traffic is steered toward the home site, as shown in Figure 40. With the ZBFW Session Reclassification feature, mid-flow inspection is not supported for stateful traffic. Note that even if only one vBond orchestrator exists in the network, it is recommended to use a Domain Name for the vBond so when additional orchestrators are added, no change of configurations are needed in the network. Using xdp-filter for high-performance traffic filtering to prevent DDoS attacks, 49.1. To resolve this issue, configure the network firewall to permit GRE protocol 47. Upgrade and activate the first upgrade group and let the code run stable for a predetermined amount of time, then proceed to upgrade and activate the additional upgrade groups over a predetermined timeframe. for packets in each direction, and for the inspect action, a policy must exist for traffic from the initiator. terminal, parameter-map zone-pair For the vBonds and vSmarts, an additional one to two devices should then be added for redundancy, and how many and where they are placed depends on the overall controller design. A warning will appear in the Multi-Site Orchestrator if the policy implemented for a site is different from the policy specified in the Multi-Site Orchestrator template. This is the pre-NAT address, and despite the name, can be a publicly routable address or a private (RFC 1918). The class-map command creates a class map to be used for matching packets to a specified class. and drop are actions. The routers also form a permanent DTLS or TLS control connection to the vManage server, but over just one of the transports. Enters the WCCP dynamically defined service identifier number. Further, check debug crypto isakmp to verify that the spoke router is sending udp 500 packet: The above debug output shows spoke router is sending udp 500 packet in every 10 seconds. Dedicated or shared pairs of WAN edge routers. A zone pair allows you to specify a unidirectional firewall policy between two security zones. Note: When running the Orchestrator as a service of the Nexus Dashboard compute cluster, the minimum ACI release for ACI fabrics onboarded on ND is 4.2(6). If the port number of the virtual gateway and the port number for the quick transmission mode are changed, use the actual configuration. Note that the number of devices a vManage can support can vary greatly depending on a number of factors, such as the number of statistics and flows that may be generated, so additional vManage instances may need to be added depending on the network demands. The first-hop leaf node where the source is connected will create the (S1,G) local state and send a PIM-Register message toward the RP. An ISR 4k router on IOS XE code can be deployed on the WAN side of an SD-WAN router to fulfill the additional requirements. To permit traffic through the firewall using a certain protocol, you can use the GUI. You can achieve affinity by using controller groups. Pinholes or ports opened through a firewall that allows applications-controlled access to a protected network are not punched In addition, the root certificate chain for the corresponding CA must also be installed for each controller before the controller certificates can be installed. Following this procedure, the setting is a permanent setting, even without the --permanent option. With anti-replay protection, IPsec packets are protected from attackers injecting or making changes to packets. Firewall_B, which receives access requests from the peer end, Firewall_A, which receives access requests from the peer end. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. In addition, there is a max-omp-sessions command under the system configuration that can also be adjusted. Interfaces that match In addition, please review the software release notes at https://www.cisco.com/c/en/us/support/routers/sd-wan/products-release-notes-list.html for more information on the specific software release before deploying. If a spine port is connected to the ISN and peering is enabled (i.e., the spine is configured as a BGP speaker), control-plane MP-BGP EVPN sessions are formed across spine nodes and across sites that have peering enabled through MP-BGP EVPN Router-IDs. Configurations and policies are applied to WAN Edge routers and vSmart controllers which enable traffic to flow between the data center and the branch or between branches. To get the list of current entries in the IP set, use the following command as root: Generate a file containing a list of IP addresses, for example: The file with the list of IP addresses for an IP set should contain an entry per line. Monitoring and tuning NIC ring buffers", Collapse section "33. The value for this variable will be defined when the device template is applied. MACsec encryption can be enabled when the requirement is to encrypt all communications between separate DC sites. Data policy, however, is directional from the perspective of the WAN Edge. SD-WAN routers can be directly connected, connected through an L2 switch, or connected through an L3 switch/router. Transports are deployed in an active/active state, and how you use them is extremely flexible. Feature access-list 102 deny ip 10.2.3.4 0.0.0.0 any access-list 102 permit any any class-map type inspect match-all test1 match access-list 102 match protocol http ! Layer 2 and Layer 3 unicast communication. Thus, from this point on the traffic will always flow in the two directions, as shown in Figure 64, in which a leaf node at a given site always encapsulates traffic and sends it toward the O-UTEP address that identifies the site to which the destination endpoint is connected. Therefore, if multiple EPGs are part of the same bridge domain and a specific policy dictates the exchange of routes for one of those EPGs, endpoint information also will be sent for all the other EPGs. Unicast traffic ingressing a Multi-Pod fabric that is part of Cisco ACI Multi-Site. This section covers information about controlling network traffic using firewalld. Information. A given flow is reclassified when a packet is received You must perform at least one step from step 5, 8, 9, or 10. policy-map You manage firewall rules for each zone independently, which enables you to define complex firewall settings and apply them to the traffic. The following deployments depict a single WAN Edge router deployed at a branch site. For more information on how to enable CloudSec encryption in a Cisco ACI Multi-Site deployment, please refer to: https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/aci_multi-site/sw/2x/configuration/Cisco-ACI-Multi-Site-Configuration-Guide-201/Cisco-ACI-Multi-Site-Configuration-Guide-201_chapter_011.html#id_79312. the access list 102 matches the deny condition and stops processing other entries in the access list. For a vManage cluster, the following ports may be used on the cluster interface of the controllers. As shown in Figure 19, the Multi-Site Orchestrator can be installed on three different form factors of the Cisco Application Services Engine. In a second data center, a standby (inactive) vManage or vManage cluster is deployed, along with at least one active vSmart controller and vBond orchestrator. Named ACL: An ACL is identified by a name. Some of the benefits include: Centralized network and policy management, as well as operational simplicity, resulting in reduced change control and deployment times. A receiver is connected in the external Layer 3 network and sends an IGMP-Join message for the same multicast group G. 8. Customizing the prefix of Ethernet interfaces during the installation, 1.6. The value 0 is used to indicate that a connection is never made to vManage over the tunnel. Layer Tunnels are restricted between pairs of data center routers and respective site groups using centralized control policies. To obtain better user experience, upgrade the browser to the latest version. A basic assumption for achieving the two goals mentioned above is that the DSCP value not be modified by the devices in the ISN, because that would make it impossible to associate the traffic to the proper QoS class once the traffic is received in a remote site. vSmart controller: The vSmart controller maintains a persistent connection to each active vManage server and every other vSmart controller, and each vSmart controller core (up to 8) maintains a persistent connection with each vBond orchestrator. These are the steps for the FortiGate firewall. The FirewallNetmeeting Refer to Additional templates - This section includes banner, Simple Network Management Protocol (SNMP), bridge, localized policy, and security policy templates. Per-filter statistics are available only for match-any filters and are not applicable for match-all cases. Network interface device naming hierarchy, 1.2. NAT can be configured to advertise only one This may create unexpected traffic path scenarios, as in the example shown in Figure 106. tcp PSH(001000): push function. inspect The leaf registers the interest of a locally connected receiver (creating a (*,G) local entry) and generates a COOP message to the spines to provide the same information. Both masquerading and SNAT are very similar. as do not match Packets that match a deny access control entry (ACE) cause an ACL process to be terminated and the next match statement within Example 3: Apply an ACL to Telnet, to allow only the administrator's host (172.16.105.2) to Telnet to the device and reject other users. From a policy perspective, there are three main scenarios to consider for the intrasubnet communication use case: EP1 and EP2 are in the same EPG and bridge domain, and no microsegmentation is configured (and the EPG is not configured as isolated): In this case, no policy is applied, and EP1 can freely communicate with EP2. Legacy network scripts support in RHEL", Expand section "14. {on | EP1 and EP2 are in two different EPGs that are part of the same bridge domain and IP subnet: In this case, communication is dictated by the contract defined between them, and as in the previous case, at steady state the policy is usually applied at ingress on the source leaf node. configure any actions for the class-default class in an inspect policy, the default action is drop. session. It provides a single pane of glass for Day 0, Day 1, and Day 2 operations. MPLS can be used for business-critical traffic, while Internet can be used for bulk traffic and other data. In a Multi-Site deployment, multiple VMMs commonly are deployed in separate sites to manage the local clusters of hypervisors. It also orchestrates the secure data plane connectivity between the WAN Edge routers by reflecting crypto key information originating from WAN Edge routers, allowing for a very scalable, IKE-less architecture. When designing configuration templates, it is helpful to think about how operations may interact with the templates on a day-to-day basis. Creating a dummy interface with both an IPv4 and IPv6 address using nmcli, 22. Service VPNs can be enabled for features such as OSPF or BGP, Virtual Router Redundancy Protocol (VRRP), QoS, traffic shaping, or policing. If you change the zone of the interface using the web console, firewall-cmd or firewall-config, the request is forwarded to NetworkManager and is not handled by firewalld. interface to a zone, VFR is configured automatically on the same interface. For more information about the Cisco ACI Multi-Site architecture, refer to the documentation available at the following link: https://www.cisco.com/c/en/us/support/cloud-systems-management/application-policy-infrastructure-controller-apic/tsd-products-support-series-home.html. Each site also has its own local GOLF L3Out connection, which advertises the subnet through its GOLF L3Out connection to its GOLF router. Allow the packets from hosts 192.168.1.2 and 192.168.1.3 to pass, and reject the packets from other hosts on network segment 192.168.1.0/24. Note: The configuration of the route-map associated to the L3Out is not done on the Cisco Multi-Site Orchestrator but must be performed at the local APIC level. In the scenario on the right, the Cisco ACI Multi-Site design is used to interconnect fabrics deployed in the same geographical location, and a shared pair of WAN edge routers is commonly used to provide connectivity to the WAN. The WAN Edge router discovers its controllers automatically and fully authenticates to them and automatically downloads its prepared configuration before proceeding to establish IPsec tunnels with the rest of the existing network. The enterprise landscape is continuously evolving. Define the egress zone to use with the policy. If you need to apply filtering more granularly at the EPG level, you must configure the EPGs in separate BDs. Each WAN Edge router connects to one transport and the WAN Edge routers are connected directly for the TLOC Extension links. Only two sites (fabrics) can currently be connected back to back. The BD must then be configured with the L2 Stretched flag disabled. Starting from Cisco ACI Release 4.2(1), it is instead possible to define the same infra L3Out to be used for GOLF and Multi-Site traffic. In tunnel mode, the VPN gateway inserts a standard UDP header between the new IP header and an ESP header. As mentioned in the previous section, starting from Cisco Multi-Site Orchestrator Release 2.2(3), it is also possible to deploy the MSO cluster in the public cloud (that is in a specific AWS region) to be able to manage from there all the ACI fabrics that are part of the Multi-Site domain. These templates can be CLI-based or feature-based. access-list 102 deny ip 10.2.3.4 0.0.0.0 any access-list 102 permit any any class-map type inspect match-all test1 match access-list 102 match protocol http ! SSH uses TCP destination port 22. Note: The combined deployment of a Cisco ACI Multi-Pod and Multi-Site architecture shown above is supported in Cisco ACI Release 3.2(1) and later. 451. To make this setting persistent, pass the. The FortiGate firewall in my lab is a FortiWiFi 90D (v5.2.2), the Cisco router an 2811 with software version 12.4(24)T8. inspect These files are copied to the /etc/firewalld/zones/ directory only after they are modified. maximum Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. is explicitly denied. seconds. Subsequently, it is advertised from the spines in site 1 to the spines in site 2, which then propagates the information to the local leaf nodes. During data transmission, the LAC uses translates the source IP address of the original packet to the VT interface address through source NAT, performs PPP encapsulation and L2TP encapsulation on the VT interface, and sends the encapsulated packet to the LNS through a public network route. The following example shows how to configure class map c1 with the match criteria of ACL 101 and HTTP protocol. Configures the match criterion for a class map based on the ACL name or number. Applications are moving to multiple clouds and are reachable over multiple transports. the return traffic. The scenario using dedicated GOLF devices raises the following deployment considerations when a common Layer 3 infrastructure is used for north-south and east-west communication. idle-time Dropping out-of-order packets can cause significant delays RHEL System Roles is a set of contents for the Ansible automation utility. They help you specify where a Cisco IOS XE firewall If no other controller groups are listed in the controller-group-list, the router loses connection to the overlay. Creating a NetworkManager dispatcher script that runs dhclient exit hooks, 44. The network administrator should install and configure a DMZ server. See https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/system-interface/ios-xe-17/systems-interfaces-book-xe-sdwan/c-template-migration.pdf for more detail. Therefore, the MTU settings in the ISN must take into account this increase as well. 1. to redirect traffic for interception. Use WAN Edge for SD-WAN traffic, non-SD-WAN traffic can come into the CE and route to the core. For branch designs, keeping the design simple is important. Configuring a network bond using RHELSystemRoles, 8.11. The following figure are two examples of an on-premise deployment. traffic, the return traffic is dropped. The differences are: The following procedure describes how to enable IP masquerading on your system. security b. For additional details on data plane security and other security topics , see https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/security/vedge/security-book/security-overview.html. The fabric administrator can tune (as part of the fabric-access policies configuration) specific properties associated to each of these user-level QoS classes, as minimum buffers, congestion algorithm, percentage of allocated bandwidth, etc. Zone-based policy firewall features for Cisco ASR 1000 Series Aggregation Services Routers are packaged separately from the Starting a service within an isolated VRF network", Expand section "42. The first important thing to notice in the figure above is that first-generation spine models (like Cisco Nexus 9336PQs or modular chassis with first-generation line cards) while supported in the Cisco ACI Multi-Pod fabric design, cannot be used when combining Cisco ACI Multi-Pod and Multi-Site. The ACI Multi-Site architecture does not allow a traffic redirection function similar to the one shown earlier in Figure 41 for traditional L3Out connections on border leaf nodes, so you must ensure that traffic coming from the WAN is always encapsulated by the GOLF routers toward the site at which the destination endpoint is located. The exception to this is if the contract has associated a service graph with Policy-Based Redirect (PBR). Understanding the teamd service, runners, and link-watchers, 7.6. In this document, ACL refers to ACL4, ACL6, and the ACL supporting both IPv4 and IPv6 packet filtering. Configuring VLAN tagging", Expand section "5. Note: Anycast RP nodes can be deployed in the external network for providing a redundant RP functionality. By default, EIGRP is not redistributed into OMP nor are routes redistributed from OMP to EIGRP, so redistribution in both directions must be explicitly configured. When Firewall_B receives the packets, the source and destination security zones are Untrust and Local. This parameter can be adjusted through the CLI, however, if need be. In this situation, an ACL name is like a domain name that represents an IP address. The new Cisco ACI Multi-Site architecture provides complete fault and change domain separation between the interconnected fabrics. Also, the source endpoint will always resolve the ARP information for its default gateway with the local leaf node to which it connects and then send the data packet destined for the remote endpoint to it. from the session initiator on an established session. IPsec is used to encrypt all intraMulti-Site Orchestrator cluster control-plane and data-plane traffic to provide security because the MSO nodes can be placed up to 150 ms RTT apart and intra-cluster communication could consequently traverse a not-secure network infrastructure. SNAT sets the source IP address of packets to a specified IP and does not dynamically look up the IP of the outgoing interface. Starting in vManage version 20.1, feature templates can no longer be shared between vEdge and IOS XE SD-WAN devices. Note: For more information on GOLF, see the documents at the following links: https://www.cisco.com/c/en/us/solutions/collateral/data-center-virtualization/application-centric-infrastructure/white-paper-c11-736899.html, https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/2-x/L3_config/b_Cisco_APIC_Layer_3_Configuration_Guide/b_Cisco_APIC_Layer_3_Configuration_Guide_chapter_010010.html.
