Maroun, OSPF routers don't really send out routes to their neighbors, they send LSAs. For most things you can think of them as being the same, except in situations like yours.
Your router is presumably creating the default route (use 'show ip ospf database' to verify) and therefore creating the LSA for it. The LSA is flooded to all neighbors. In a redundant network the LSA could even be sent from multiple neighbors. The end result is that all routers WILL get the default gateway LSA. To get around this "problem", you need to use a distribution list on the router that should not honor the default gateway. The router will still get the LSA, will still enter the LSA into its database and will still flood the LSA to its neighbors. But if you use a distribution list it will NOT put the route in its routing table. It sounds like this is what you're looking for. In other words put the filter on the router where the filtering needs to take place, not on the sending router. You could also accomplish this by using multiple areas and filtering at the ABR. - Tom Maroun Waked wrote: > hi, > > I have a router running ospf that needs to send a > default route to its neighbors.
