Add Path on Tenant BGP Peer

About this task

Follow this procedure to add paths on tenant BGP peer.

1. To configure an additional path when you create a BGP peer, run the following command:
   

   efa tenant service bgp peer create --name <bgp-peer-name> --tenant <tenant-name> 
           --ipv6-uc-nbr-add-path-capability <device-ip,vrf-name:neighbor-ip,
                  {send | receive | both}>
           --ipv6-uc-nbr-add-path-advertise-all <device-ip,vrf-name:neighbor-ip,
                  {true | false}>
           --ipv6-uc-nbr-add-path-advertise-group-best <device-ip,vrf-name:neighbor-ip,
                  {true | false}>
           --ipv6-uc-nbr-add-path-advertise-best <device-ip,vrf-name:neighbor-ip,
                  2-16>

2. To configure an additional path when you update a BGP peer, run the following command:
   

   efa tenant service bgp peer update --name <bgp-peer-name> --tenant <tenant-name> 
           --ipv4-uc-nbr-add-path-capability <device-ip,vrf-name:neighbor-ip,
                  {send | receive | both}>
           --ipv4-uc-nbr-add-path-advertise-all <device-ip,vrf-name:neighbor-ip,
                  {true | false}>
           --ipv4-uc-nbr-add-path-advertise-group-best <device-ip,vrf-name:neighbor-ip,
                  {true | false}>
           --ipv4-uc-nbr-add-path-advertise-best <device-ip,vrf-name:neighbor-ip,
                  2-16>

3. Verify the configuration on the SLX device.
