To change the bodyweight for all incoming routes, use the “bodyweight” solution Using the neighbor command right after forming the BGP peer associations.
R2(config)#router bgp one hundred
R2(config-router)#neighbor a hundred.1.1.1 remote-as ten
R2(config-router)#neighbor a hundred.1.one.1 body weight two hundred
