Hi Victor,
No I am not running Frame Relay.This is all ethernet broadcast and though the doc does specify that it pertains to broadcast network type as well it also says that the routers in question did not have the route in their routing table. In my case I am seeing the route in the routing table and am also able to get to the advertising router.
can you please explain the layout of the database. if you notice that under area 0 it doesn't give that message however under the LSA's for Area 13 it gives that message. Does that mean that the advertising router is not reachable via Area 13.
thx
