Julius -
As Chris mentioned early on, the key difference with OSPF is that the database
needs to be synchronized across all routers. Given that, you have the
abilility to summarize external routes, between areas or a LSA filtering
between areas, as Brian mentioned. And, the various stub areas, as Victor
mentioned. Therefore, if you inject or suppress a route...you suppress/inject
it throughout the entire network. HTH.

Subject: RE: Summarization
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.

Is it possible to send a summary to a specific

a
BGP suppress and unpsupress map for two different
neighbors?
