Description
Use the
peer preferred-value
command to assign a preferred value to routes received from a peer or
peer group.
Use the
undo peer preferred-value
command to restore the default value.
The default preferred value is 0.
Routes learned from a peer have an initial preferred value. Among multiple routes that have the same
destination/mask and are learned from different peers, the one with the greatest preferred value is
selected as the route to the destination.
Note that:
If you both reference a routing policy and use the
peer
{
group-name | ip-address
}
preferred-value
value
command to set a preferred value for routes from a peer, the routing policy sets a specified
non-zero preferred value for routes matching it. Other routes not matching the routing policy uses the
value set with the command. If the preferred value specified in the routing policy is zero, the routes
matching it will also use the value set with the command. For information about using a routing policy
to set a preferred value, see the command
