For ACI WAN Interconnect peers, increase this as needed. The default bgpPeerPfxPol policy restricts routes to 20, 000. The static route should be the same as the route received through the other link. Also, if the DCI is dual-homed to the same pod, then the precedence (administrative distance) of In this case, define a static route on the ASR for the Switches to the ASR have the next hop as the PTEP of the leaf switch. If there is direct peering between a spine switch and a data center interconnect (DCI) router, the transit routes from leaf Source has interfaces on a spine switch, the transit prefix gets sent from a non-GOLF 元Out to the GOLF router with the wrong If you have an ERSPAN session that has a SPAN destination in a VRF instance, the VRF instance has GOLF enabled, and the ERSPAN This is the same as existing 元extOut on leaf switches for tenants. When deploying three GOLF Outs, if only 1 has a provider/consumer label for GOLF, and 0/0 export aggregation, APIC will export all routes. The BGP EVPN session in the matching provider 元Out in the infra tenant advertises the tenant routes defined in this 元extOut. Also, in this case, the OSPF Area has to be different on each of the 元extOuts and use different loopback addresses. When configuring GOLF on a spine switch, wait for the control plane to converge before configuring GOLF on another spine switch.Ī spine switch can be added to multiple provider GOLF outside networks ( GOLF 元Outs), but the provider labels have to be different for each GOLF 元Out. Since the 2.1(1) release, the two featuresĬan be deployed together over all the switches used in the multipod and EVPN topologies. N9000K switches without “EX” on the end of the switch name for example, N9K-9312TX. In release 2.0 (2) the two features are supported in the same fabric only over Cisco Nexus Up to APIC release 2.0(2), GOLF is not supported with multipod. With Cisco APIC, release 3.1(x) and higher, this includes the N9K-C9364C switch.Īt this time, only a single GOLF provider policy can be deployed on spine switch interfaces for the whole fabric. Switches and the external routers until Cisco ACI receives a route from the external routers.Īll Cisco Nexus 9000 Series ACI-mode switches and all of the Cisco Nexus 9500 platform ACI-mode switch line cards and fabric GOLF routers must advertise at least one route to Cisco ACI in order to accept traffic. Observe the following GOLF guidelines and limitations: The BGP EVPN session in the matching provider 元extOut in the infra tenant advertises the tenant routes defined in this 元Out. Label matching enables application EPGs in other tenants to consume the LNodeP external 元Out EPG. The bridge domain subnet must be set to advertise externally and it must be in the same VRF as the application EPG and theĬommunication between the application EPG and the GOLF 元Out EPG is governed by explicit contracts (not Contract PreferredĪn l3extConsLbl consumer label that must be matched with the same provider label of an 元Out for GOLF in the infra tenant. The scope of the subnet is used to control import/export route control and security policies. The 元extOut defined in regular tenants requires the following:Īn l3extInstP (EPG) with subnets and contracts. )Ī provider label for the 元extOut for GOLF in the infra tenant.Īll regular tenants use the above-defined physical connectivity. LNodeP ( l3extInstP is not required within the 元Out in the infra tenant. Transit routing with shared services using GOLF is not supported.Ī Layer 3 external outside network ( 元extOut) for GOLF physical connectivity for a spine switch is specified under the infra tenant, and includes the following: Subinterfaces configured on spine fabric ports. The network is extended out using Layer 3 Of tenant BGP sessions and the amount of configuration required for all of them. Of tenant BGP sessions towards the Data Center Interconnect Gateway (DCIG) improves control plane scale by reducing the number It uses the BGP EVPN protocol over OSPF for WAN routers that are connected to spine switches.Īll tenant WAN connections use a single session on the spine switches where the WAN routers are connected. The Cisco ACI GOLF feature (also known as Layer 3 EVPN Services for Fabric WAN) enables much more efficient and scalable ACI fabric WAN connectivity.
