Configure IP Prefix List and Route Map on Tenant BGP Peer Group

To enable external connectivity, you can configure the IP prefix list and route map attributes in ingress or egress direction when you create or update BGP peer group.

About this task

Follow this procedure to configure IP prefix list and route map attributes.

Procedure

  1. Run the following command to configure IP prefix list and route map attributes when you create 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-prefix-list <device-ip,pg-name:prefix-list-name,direction>
    --pg-ipv4-uc-nbr-route-map <device-ip,pg-name:route-map-name,direction>
                
    --pg-ipv6-uc-nbr-prefix-list <device-ip,pg-name:prefix-list-name,direction>
    --pg-ipv6-uc-nbr-route-map <device-ip,pg-name:route-map-name,direction>

    The following example configures IP prefix list and route map:

    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-prefix-list 10.20.246.15,pg1:ipPrefixList1,in
    --pg-ipv6-uc-nbr-prefix-list 10.20.246.15,pg1:ipPrefixList2,out 
    --pg-ipv4-uc-nbr-route-map 10.20.246.15,pg1:routeMap2,in 
    --pg-ipv6-uc-nbr-route-map 10.20.246.15,pg1:routeMap1,in 
           
    --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-prefix-list 10.20.246.16,pg1:ipPrefixList1,in
    --pg-ipv6-uc-nbr-prefix-list 10.20.246.16,pg1:ipPrefixList1,out 
    --pg-ipv4-uc-nbr-route-map 10.20.246.16,pg1:routeMap1,in 
    --pg-ipv6-uc-nbr-route-map 10.20.246.16,pg1:routeMap1,out
  2. Run the following command to configure IP prefix list and route map attributes when you update 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-prefix-list <device-ip,pg-name:prefix-list-name,direction>
    --pg-ipv4-uc-nbr-route-map <device-ip,pg-name:route-map-name,direction>
                
    --pg-ipv6-uc-nbr-prefix-list <device-ip,pg-name:prefix-list-name,direction>
    --pg-ipv6-uc-nbr-route-map <device-ip,pg-name:route-map-name,direction>

    The following example configures IP prefix list and route map:

    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-prefix-list 10.20.246.15,pg2:ipPrefixList2,out 
        --pg-ipv4-uc-nbr-route-map 10.20.246.15,pg2:routeMap2,in
                  
        --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-prefix-list 10.20.246.16,pg2:ipPrefixList1,out 
        --pg-ipv4-uc-nbr-route-map 10.20.246.16,pg2:routeMap1,in
