Add Path on Tenant BGP Peer Group

You can add paths on tenant BGP peer group.

About this task

Follow this procedure to configure additional paths (for both IPv4 and IPv6) when you create or update a BGP peer-group.

Procedure

  1. To configure an additional path when you create a BGP peer-group, run the following command: 
    efa tenant service bgp peer-group create --name <bgp-pg-name> --tenant <tenant-name>
   --pg-ipv4-uc-nbr-add-path-capability <device-ip,pg-name:{send | receive | both}>
   --pg-ipv4-uc-nbr-add-path-advertise-all <device-ip,pg-name:{true | false}>
   --pg-ipv4-uc-nbr-add-path-advertise-group-best <device-ip,pg-name:{true | false}>
   --pg-ipv4-uc-nbr-add-path-advertise-best <device-ip,pg-name: 2-16>
  2. To configure an additional path when you update a BGP peer-group, run the following command: 
    efa tenant service bgp peer-group update --name <bgp-pg-name> --tenant <tenant-name> 
   --pg-ipv4-uc-nbr-add-path-capability <device-ip,pg-name:{send | receive | both}>
   -pg-ipv4-uc-nbr-add-path-advertise-all <device-ip,pg-name:{true | false}>
   -pg-ipv4-uc-nbr-add-path-advertise-group-best <device-ip,pg-name:{true | false}>
   -pg-ipv4-uc-nbr-add-path-advertise-best <device-ip,pg-name: 2-16>
  3. Verify the switch configuration on the SLX device.
