Setting up the ASBR in an NSSA area will work. We connected a Nortel CVX to two Extreme Networks Layer 3 switches acting as the ABR'S then off to two more layer 2 switches then to two Cisco 7200 routers in a lab. We were able to keep the LSA type 7's in the NSSA area. It works just fine. With the Extreme L3 boxes we could use the translate option to translate LSA type 7 to LSA type 5 through the ABR's.

[7:12212] Could you accomplish this by making the area containing the ASBR a stubby area? IIRC, you can put an ASBR inside a stubby area but the Type-5 LSAs will not leave the area. I'm not sure about that, but I'd swear I read that somewhere recently. Okay, I just checked this in Giles, 2nd edition. According to him, the above is true. But who knows if it works in the real world. Good luck! John >>> "[EMAIL PROTECTED]" 7/12/01 1:58:11 PM >>> hi all, have a problem that has been nagging at me for a good long time now... say you have a pair of ABRs sitting at an OSPF area boundary, and an ASBR is originating Type-5 LSAs from inside the non-backbone area. Is there an easy way to suppress the propagation of the type-5s outside the area? I would have a range statement on the ABRs to advertise the area aggregate, I just want to suppress the more specifics. I have tried using 'distribute-list out ' which would do it for me, but for some reason IOS won't allow this with OSPF: router(config)#router os 1 router(config-router)#distribute-list 1 out FastEthernet 0/0 % Interface not allowed with OUT for OSPF router(config-router)# I suppose that allowing this could potentially screw up routing if done without some care, but JunOS lets you do exactly this sort of thing - you can produce some wacky policies, but at least you have the option ;-) btw - I know I could prolly do this with multiple OSPF instances and redistribute between them, but I *really* don't want to get into this level of complexity. thanks in advance - this one has been driving me mad Andy Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=12236&t=12236 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
