Configure Backup Routing Neighbors on BGP Peer

You can configure backup routing neighbors with additional attributes, such as bidirectional forwarding detection, route-maps and prefix-lists. By default, backup routing neighbor is configured with remote-as and next-hop-self. You can provide md5-password as a fabric setting which is applied on the neighbors.

About this task

Follow this procedure to configure backup routing neighbors on BGP peer.

Note

You can modify the MD5 password for the backup routing neighbors only by configuring and re-configuring the fabric.

Procedure

To create backup routing neighbors when you create a BGP peer, run the following command:

efa tenant service bgp peer create --name <bgp-peer-name> --tenant <tenant-name>
      --ipv4-uc-nbr <device-ip,vrf-name:neighbor-ip,remote-asn>
      --ipv4-uc-nbr-bfd <switch-ip,vrf-name:ipv4-neighbor,bfd-enable(t/f),bfd-interval,bfd-rx,bfdmult>
      --ipv4-uc-nbr-default-originate <device-ip,vrf-name:neighbor-ip,true/false>
      --ipv4-uc-nbr-default-originate-route-map <device-ip,vrf-name:neighbor-ip,route-map>

To create backup routing neighbors when you update a BGP peer, run the following command:

efa tenant service bgp peer update --name <bgp-peer-name> --tenant <tenant-name>
      --operation peer-add --ipv4-uc-nbr <device-ip,vrf-name:neighbor-ip,remote-asn>
      --ipv4-uc-nbr-bfd <switch-ip,vrf-name:ipv4-neighbor,bfd-enable(t/f),bfd-interval,bfd-rx,bfdmult>
      --ipv4-uc-nbr-default-originate <device-ip,vrf-name:neighbor-ip,true/false>

To remove the backup routing neighbors association with BGP service when you delete a BGP peer, run the following command:
```
efa tenant service bgp peer delete --name <bgp-peer-name> --tenant <tenant-name>
```
