By default, an EBGP route has a
preference of 255.
Configuring the default local preference
The local preference is used to determine the optimal route for traffic leaving the local AS. When a

This task allows you to specify the default local preference for routes sent to IBGP peers.
To specify the default local preference (IPv4 unicast/multicast address family):
