I don't know what that's in response too. Yes, the ASBR can have a static default route configured and with the default-info orig it can inject that into the OSPF domain. That way the routers in the OSPF domain can send traffic to the Internet. As I said before, we haven't addressed traffic coming back from the Internet into the OSPF domain, though. Assuming a simple design, the ISP can have a static route to the network in question and the OSPF routers can do their "magic" to figure out the details of where the packets should go. :-) Priscilla > > ""Priscilla Oppenheimer"" a icrit dans > le message de > news: [EMAIL PROTECTED] > > hanan wrote: > > > > > > Hello > > > Thank for your reply > > > Do I need to create route redistribution in my ASBR router? > > > As I said the ASBR router has 2 interface one connected to > my > > > internal > > > network in single area and the other interface is connected > to > > > ISP so do I > > > need to create route redistribution or its not necessary? > > > > Nope, no need to do route redistribution.
