Configure IPv6 Address as Update Source

About this task

Follow this procedure to configure IPv6 address as an update-source in the XCO fabric.

Starting from XCO 3.4.0 and SLX 20.5.30 and later, tenant BGP peer-groups support both IPv4 and IPv6 addresses as an update-source. The feature is supported on the following platforms: Extreme 8520, SLX 9540 or 9640, SLX 9150 or 9250, SLX 9740, Extreme 8820, and Extreme 8720.

Note

• XCO version 3.4.0 does not support Dual IPv6 addresses, which is IPv6 plus IPv4 formats.
• XCO versions below 3.4.0 and SLX versions below 20.5.3 support update-source attribute for tenant BGP peer-groups, but only IPv4 address can be configured as update-source.

1. Run the following command to configure IPv6 address as an update-source when you create a BGP peer-group:
   

   efa tenant service bgp peer-group create --tenant <tenant-name> --name <peer-group-name> 
                  --pg-name device-ip:peer-group-name --pg-update-source-ip device-ip,peer-group-name:update-source-ip

2. Run the following command to configure IPv6 address as an update-source when you update a BGP peer-group:
   

   efa tenant service bgp peer-group update --tenant <tenant-name> --name <peer-group-name> --operation peer-group-add
                  --pg-name device-ip:peer-group-name --pg-update-source-ip device-ip,peer-group-name:update-source-ip

Example

efa tenant service bgp peer-group create --tenant "tenant1" --name "bgpPeerGroup2" 
             --pg-name 10.20.246.15:bgppg2 --pg-asn 10.20.246.15,bgppg2:100 --pg-update-source-ip 10.20.246.15,bgppg2:10::10
efa tenant service bgp peer-group update --tenant "tenant1" --name "bgpPeerGroup2" --operation peer-group-add
             --pg-name 10.20.246.15:bgppg1 --pg-asn 10.20.246.15,bgppg1:200 --pg-update-source-ip 10.20.246.15,bgppg1:10::20

efa tenant service bgp peer-group show --tenant tenant1 –detail
