Another command that will actually filter the route out of the LSA is the
area filter-list command. As you already know, the distribute-list feature
will keep the route out of the routing table, the area filter-list command
removes the route from the LSA and completely prevents the advertisement of
the route into or out of an area, on an ABR. So, this works for INTERAREA
routes, but it worked as tested for me. Here's the link:

Watch the wrap.

Subject: OSPF Inbound Filtering Using Route Maps with a Distribute List
> Hello everybody,
>
> I've been using this new feature (OSPF Inbound Filtering Using Route Maps

> R4 has two OSPF LSAs to 150.6.5.5/32. One of the LSAs i received in a BRI

> I don't want to have the ISDN route in my IP routing table, so i have

> !
> route-map LOOP_ISDN deny 10
> match ip address prefix-list LOOP_5
> match interface BRI0/0
> !
> route-map LOOP_ISDN permit 20

> router ospf 1
> distribute-list route-map LOOP_ISDN in

> This route-map is supposed to delete the route that has the BRI interafce
