Configuration guidelines
Create a peer group before configuring basic functions for it. For related information, see " Configuring
IPv6 BGP peer group ."

interfaces.

Configuring a preferred value for routes from a peer or peer
group
If you both reference a routing policy and use the command peer { group-name | ipv6-address }
preferred-value value to set a preferred value for routes from a peer, the routing policy sets the specific
preferred value for routes matching it. If the preferred value in the routing policy is zero, the routes use the
value set with the peer { group-name | ipv6-address } preferred-value value command. For information
about using a routing policy to set a preferred value, see the command peer { group-name |
ipv4-address | ipv6-address } route-policy route-policy-name { import | export } in this document, and
the command apply preferred-value preferred-value in Layer 3—IP Routing Command Reference.
To configure a preferred value for routes from a peer or peer group:
