Users Guide

When an aggregate address is denied using a peer's outbound route-map, individual routes suppressed by
the aggregate address are advertised to that peer.
The attribute-map corresponding to an aggregate address is applied during the outbound update creation
time; hence the value set in that attribute-map will not be shown in the output of the show ip bgp
aggregate route command.
