Configuring a Shortcut Route

An eBGP route received has a priority of 255, lower than a local route. This task allows you configure an
eBGP route as a shortcut route that has the same priority as a local route and thus has greater likehood
to become the optimal route.
Follow these steps to configure a shortcut route:

Configuring BGP Route Attributes

Prerequisites
BGP connections have been created.

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/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:
To do...
Enter system view
Enter BGP view
Specify a preferred value for
routes received from a peer or
peer group

Configuring Preferences for BGP Routes

A router may run multiple routing protocols, each of which has a preference specified. If they find the
same route, the route found by the routing protocol with the highest preference is selected.
This task allows you configure preferences for external, internal, local BGP routes and reference a route
policy to set preferences for matching routes as needed.
