The "COMMUNITY" attribute is being sent to this neighbor and it is being set to NO-EXPORT for any routes exept the ones which match ACL 101 via the logiic in route-map SetCommunity. NO-EXPORT means : don't advertise this route to any ohter AS's. The "HOST 255.255.0.0" in the destination of an extended ACL is a weird sort of "shorthand" meaning "only this aggrigate and not routes which are more spcecific".
Does anyone know the meaning of 10.0.0.0 0.255.255.255 0.0.0.0 0.0.0.0 ?????
