The feature lets you add or delete anycast-ipv4 and anycast-ipv6 to or from an existing tenant network.
You can add or delete the anycast-ipv4 and anycast-ipv6 using the EPG update anycast-ip-add/delete operations on an L3 EPG.
You can provide ipv6 nd attributes (ipv6 nd mtu, ipv6 nd prefix, ipv6 nd m/o flags) along with anycast-ipv6 during anycast-ip-add operation.
You can provide only one anycast-ipv4 and one anycast-ipv6 per tenant network even though SLX supports multiple anycast-ipv4/ipv6 per VE.
Typical usage of the API from Openstack Integration is as follows:
efa tenant epg update --name <epg-name> --tenant <tenant-name> 
                --operation <anycast-ip-add | anycast-ip-delete> 
                --anycast-ip <ctag:anycast-ipv4> --anycast-ipv6 <ctag:anycast-ipv6>
            Example
efa tenant epg show --detail
