RE: OSPF route filtering on ABRs...

hi,
since ospf is a link-state protocol, using distribue-list out ospf is rather
useless because ospf does not propagate routing table out its interface but
link states. Therefore, downstream routers will still receive the link
states and generate the routes. cheers

Hi,
   I think if you want to filter all of the routes from area 0 into the
area1 ,
you could config the ABR a totally-stubby area;
   I couldn't be sure that you may use distribute-list xxx out ospf xxx
to filter partial toutes from area 0 into area 1, if you get answer, pls
tell me.
