5.2.4 Configuring route filtering of peer (group)
Quidway S3500 series switches support filtering imported and advertised routes for
peers (groups) through Route-policy, AS path list , ACL and ip prefix list.
The route filtering policy of advertised routes configured for each member of a peer
group must be same with that of the peer group but their route filtering policies of
