HP VPN Firewall Appliances Network Management Command Reference

508
Usage guidelines
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.
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 the specified 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 peer { group-name | ip-address } preferred-value value command. For information
about using a routing policy to set a preferred value, see commands peer { group-name | ip-address }
route-policy route-policy-name { export | import } and apply preferred-value preferred-value.
