Redistribution causes router b to become an ASBR and thus it generates type 5 (external) LSAs. But don't the ABRs have to generate type 4 (summary asbr) LSAs into their respective areas before those type 5s are of any use? I don't think it's one or the other (ASBR external or ABR summary).

He has to do something of that sort. Redistributing the static route should work. Other methods would work too, if we knew more about his OSPF network. Theoretically, Router B is an ASBR.

Re: Simple static route redistribution [7:54040]
Priscilla, After rereading the question, I see my mistake. I guess I just read right over the part where he said there was no route from B to A. Those pesky details will get you every time.

RE: Simple static route redistribution [7:54040]
Won't he also need to redistribute the static route on router b into OSPF, so that the rest of the OSPF area learns the route?

Router B knows how to route packets into its OSPF domain, so that won't be a problem, but have you considered the replies from the OSPF side going back to Router A? You'll need a static route on Router B pointing back the other way, and then it should all work fine. ___ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com > Since ive got a static route pointing > to b, i guess that B will do a lookup on the destination and route as > persay.

Re: Simple static route redistribution [7:54040]
I disagree - how does router B know to route traffic back to router A? Router B will need some static route back to Router A, or some other IGP needs to run between A and B. As it is now, traffic *can* get from router A to the OSPF cloud, but not back.

Re: Simple static route redistribution [7:54040]
Anthony, If I understand you correctly, it shouldn't be a problem. All you're doing is mixing dynamic with static routing. It's done every day, all over the world. By the way, how do you like your Extreme equipment. Where I used to work did a migration to Extreme (or rather has been doing a migration to Extreme for over a year now, DOH!). Just wondering if you've had better luck than them. :) ""evans Anthony"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hi all, > > Just a quick question: > > I have the following setup: (a)(b)---OSPF network > > Router A (extreme L3 switch) is connected to router B, and router B is > running ospf to other cisco boxes.
