Configure remove-private-as on BGP Peer Group

To enable external connectivity, you can configure the remove-private-as attribute when you create or update BGP peer group.

By default, remove-private-as is disabled.

Procedure

  1. Run the following command to create a BGP Peer-Group on a tenant VRF: 
    efa tenant service bgp peer-group create --name <bgp-pg-name> --tenant <tenant-name>
                   --pg-name <device-ip:pg-name> --pg-asn <device-ip,pg-name:remote-asn>
                   --pg-bfd-enable <device-ip,pg-name:true|false> 
                   --pg-remove-private-as <device-ip,pg-name:true|false>
  2. Run the following command to update a BGP Peer-Group on a tenant VRF: 
    efa tenant service bgp peer-group update --name <bgp-pg-name> --tenant <tenant-name> 
                   --operation peer-group-add 
                   --pg-name <device-ip:pg-name> --pg-asn <device-ip,pg-name:remote-asn>
                   --pg-bfd-enable <device-ip,pg-name:true|false> 
                   --pg-remove-private-as <device-ip,pg-name:true|false>
    Example:
    efa tenant service bgp peer-group create --name ten1bgppg1 --tenant ten1 
                   --pg-name 10.20.246.15:pg1 --pg-asn 10.20.246.15,pg1:55001 
                   --pg-bfd-enable 10.20.246.15,pg1:true 
                   --pg-remove-private-as 10.20.246.15,pg1:true 
                   --pg-name 10.20.246.16:pg1 --pg-asn 10.20.246.16,pg1:55001 
                   --pg-bfd-enable 10.20.246.16,pg1:true 
                   --pg-remove-private-as 10.20.246.16,pg1:true

efa tenant service bgp peer-group update --name ten1bgppg1 --tenant ten1 
                   --operation peer-group-add 
                   --pg-name 10.20.246.15:pg2 --pg-asn 10.20.246.15,pg2:55002 
                   --pg-bfd-enable 10.20.246.15,pg2:true 
                   --pg-remove-private-as 10.20.246.15,pg2:true 
                   --pg-name 10.20.246.16:pg2 --pg-asn 10.20.246.16,pg2:55002 
                   --pg-bfd-enable 10.20.246.16,pg2:true 
                   --pg-remove-private-as 10.20.246.16,pg2:true
