The weight is usually altered on an individual route through a route-map, or it can be established for a unique bodyweight for all routes received from a given neighbor. To alter the excess weight for all incoming routes, utilize the “fat” possibility Together with the neighbor command immediately after forming the BGP peer relationships.
R2(config)#router bgp one hundred
R2(config-router)#neighbor one hundred.one.one.1 remote-as 10
R2(config-router)#neighbor a hundred.one.one.one bodyweight two hundred
