Configure default-originate to advertise default route on BGP Peer

  1. Run the following command to create a BGP Peer on a tenant VRF:
    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 <device-ip,vrf-name:neighbor-ip,true|false> 
    
              		 --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>
  2. Run the following command to update a BGP Peer on a tenant VRF:
    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 <device-ip,vrf-name:neighbor-ip,true|false> 
    
               		--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>
    Note

    Note

    The ipv4-uc-nbr-default-originate-route-map attribute is an optional attribute.
    Example:
    efa tenant service bgp peer create --name ten1bgppeer1 --tenant tenant11 
    		--ipv4-uc-nbr 10.20.246.3,v1:10.20.30.40,50000 
    		--ipv4-uc-nbr-bfd 10.20.246.3,v1:10.20.30.40,true 
    		--ipv4-uc-nbr-default-originate 10.20.246.3,v1:10.20.30.40,true 
    		--ipv4-uc-nbr 10.20.246.4,v1:10.20.30.40,50000 
    		--ipv4-uc-nbr-bfd 10.20.246.4,v1:10.20.30.40,true 
    		--ipv4-uc-nbr-default-originate 10.20.246.4,v1:10.20.30.40,true 
    		--ipv4-uc-nbr-default-originate-route-map 10.20.246.4,v1:10.20.30.40,rmap1
