   For the purpose of route selection, allows comparison of MED attribute values in routing information received from different ASs.

2. (config-router-af)# neighbor 3ffe:172:16:2::2 weight 20

   (config-router-af)# neighbor 3ffe:10:2:2::2 weight 20

   (config-router-af)# neighbor 3ffe:10:1:2::2 weight 10

   (config-router-af)# neighbor 3ffe:192:168:2::2 weight 10

   Specifies a weight for the routes learned from each peer.

   Gives priority to routes learned from an external peer over routes learned from an internal peer.
