Its perfectly fine, but a Totally stubby area doesn't get any routes injected
into it other than a default route. I want all the networks that I advertise
to be there just not this specific route to a specific neighbor. Im looking
for the least painful way other than going around onto every router and doing
inbound filtering.

Please excuse to put my nose here, being less specific what about Totally
Stubby Areas (w/or wo NSSA)

Brian McGahan escribis:

        It also depends what the topology looks like. If the summarization is
        internal on an abr you could filter it out to other areas with an lsa-3
        filter (area filter-list).

                In terms of LSA origination, no, as all routers in an OSPF area need

        to

                have
                the same database to work with.

                However depending on what you want to do, there are options like

        filtering

                routes out of specific router's routing tables, or doing something

        like

                using the neighbor database-filter command could have an effect.

                It all depends on exactly what you want to achieve.
