Configuring a shortcut route
An eBGP route received has a priority of 255, which is lower than a local route. This task allows you to
configure an eBGP route as a shortcut route. It has the same priority as a local route and is more likely
to become the optimal route.

Specifying a preferred value for routes received
By default, routes received from a peer have a preferred value of 0. Among multiple routes that have the
same destination and mask and are learned from different peers, the one with the greatest preferred
value is selected as the route to the destination.
Follow these steps to specify a preferred value for routes from a peer or peer group:
