When a BGP router summarizes a route, it does not advertise the AS path information from before the aggregation. This usually required where BGP peers are separated by certain number of hops that aren't participating in BGP - so they don't know the route to the destination network that is advertised by BGP. You’re peering with your neighbor through a BGP connection, and because it’s an advertisement, you want an export policy:. 0/0 1 set route-map name "filter" permit 1 set match ip 1 exit.
