When the local routes need to be advertised to the peer, you can implement this configuration to add the specified network segment to the BGP4+ routing table. This configuration is available only when the routes are in the local routing table.
The local routes to be advertised should be in the local IPv6 routing table. You can use routing policies to control the routes to be advertised more flexibly.
