Parameters
ipv6-group-name: Name of a peer group, a string of 1 to 47 characters.
ipv6-address: IPv6 address of a peer.
value: Preferred value, in the range of 0 to 65535.
Description
Use peer preferred-value to assign a preferred value to routes received from a peer or peer group.
Use undo peer preferred-value to restore the default.
By default, routes received from a peer or peer group have a preferred value of 0.
Routes learned from peers each have an initial preferred value. Among multiple routes to the same
destination, the route with the biggest value is selected.
If you both reference a routing policy and use the command peer { ipv6-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 { ipv6-group-name | ipv6-address } preferred-value value command. For how to
use 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 "Routing policy configuration commands."
Examples
# Configure the preferred value as 50 for routes from peer 1:2::3:4.

Parameters
ipv6-group-name: Name of a peer group, a string of 1 to 47 characters.
ipv6-address: IPv6 address of a peer.
Description

numbers.
Use undo peer public-as-only to allow IPv6 BGP updates to a peer/peer group to carry private AS
numbers.
