m. (Optional) In a VLT deployment, on each leaf switch, configure the number of multi-hop peer routes in ROUTER-BGP-NEIGHBOR mode to ensure that the BGP EVPN peer session establishes over the VLT VTEP peer if all local links to spine switches are down. OS10(conf-router-neighbor)# ebgp-multihop 1 2. Configure EVPN. An EVPN instance (EVI) spans across the VTEPs that participate in the EVPN. In OS10, configure an EVI in auto-EVI or manual configuration mode. • Auto-EVI mode a. Enable the EVPN control plane in CONFIGURATION mode. evpn b. Enable auto-EVI creation for overlay virtual networks in EVPN mode. Auto-EVI creation is supported only if BGP EVPN is used with 2-byte AS numbers and if at least one BGP instance is enabled with the EVPN address family. No further manual configuration is allowed in auto-EVI mode. auto-evi • Manual EVI configuration mode a. Enable the EVPN control plane in CONFIGURATION mode. evpn b. Manually create an EVPN instance in EVPN mode. The range is from 1 to 65535. evi id c. Configure the Route Distinguisher in EVPN EVI mode. rd {A.B.C.D:[1-65535] | auto} Where: ○ rd A.B.C.D:[1-65535] configures the RD with a 4-octet IPv4 address then a 2-octet-number. ○ rd auto automatically generates the RD. d. Configure the RT values in EVPN EVI mode. route-target {auto | value [asn4] {import | export | both}} Where: ○ route-target auto auto-configures an import and export value for EVPN routes. ○ route-target value [asn4]{import | export | both} configures an import or export value for EVPN routes in the format 2-octet-ASN:4-octet-number or 4-octet-ASN:2-octet-number. ▪ The 2-octet ASN number is 1 to 65535. ▪ The 4-octet ASN number is 1 to 4294967295. To configure the same value for the RT import and export values, use the both option. asn4 advertises a 2-byte AS number as a 4-byte route target value. If you specify the asn4 option, configure the VXLAN network ID associated with the EVPN instance in EVPN EVI mode, from 1 to 16,777,215. Configure the same VNI value that you configure for the VXLAN virtual network. For more information, see Configure VXLAN. vni vni 3. Verify the BGP EVPN configuration.
