Controlling BGP path selection

By configuring BGP path attributes, you can control BGP path selection.

Specifying a preferred value for routes received

Perform this task to set a preferred value for specific routes to control BGP path selection.
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 optimal route.
To specify a preferred value for routes from a peer or peer group (IPv4):
