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