Configure Send-Community on Tenant BGP Peer Group

To enable external connectivity, you can configure the send-community attribute when you create or update the BGP peer group.

About this task

Follow this procedure to configure send-community on tenant BGP peer group.

Procedure

  1. Run the following command to configure send-community when you create a BGP peer group: 
    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-ipv4-uc-nbr-send-community <device-ip,pg-name:
         all|both|extended|large|standard|large-and-extended|large-and-standard>
    --pg-ipv6-uc-nbr-send-community <device-ip,pg-name:
         all|both|extended|large|standard|large-and-extended|large-and-standard>
  2. Run the following command to configure send-community when you update a BGP peer group: 
    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-ipv4-uc-nbr-send-community <device-ip,pg-name: all|both|extended|large|standard|large-and-extended|large-and-standard> --pg-ipv6-uc-nbr-send-community <device-ip,pg-name: all|both|extended|large|standard|large-and-extended|large-and-standard>

    The following is an example output of configuring send-community when you create or update a BGP peer group:

    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-ipv4-uc-nbr-send-community 10.20.246.15,pg1:standard
    --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-ipv4-uc-nbr-send-community 10.20.246.16,pg1:extended


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-ipv6-uc-nbr-send-community 10.20.246.15,pg2:all
    --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-ipv6-uc-nbr-send-community 10.20.246.16,pg2:both
