ip-address— Neighbor's IP address.
peer-group-name— Name of the peer group. See section 8-19.
route-map-name— Name of the route map used to select routes to be unsuppressed.
Purpose: When the aggregate-address command is used with the summary-only option, the more-specific routes of the aggregate are suppressed (see section 1-7). The aggregate-address summary-only command suppresses the more-specific routes to all neighbors. You can use an unsuppress map to selectively leak more-specific routes to a particular neighbor.
