Route-map matching OSPF router ID

It is possible to use a route-map to match prefixes that have been sent by a particular OSPF router based on the OSPF router ID of that device. The match statement to use is the following:

match ip route-source

When a match is done on the route source, the route source represents the OSPF Router ID of the LSA originator of the LSA in which the prefix is advertised.
