Re: OSPF NSSA [7:38881]
Hi all, I meant to reply earlier but was busy with work. Finally, managed to squeeze in some time during the weekend to test out the NSSA stuff again. Thanks to all who replied and especially to Chris who confirmed that it is a bug. Attached are two links that I find useful in the course of studying OSPF NSSA. OSPF NSSA http://www.cisco.com/warp/public/104/nssa.html How Does OSPF Generate Default Route http://www.cisco.com/warp/public/104/21.html Regards, cheekin - Original Message - From: Chris Camplejohn To: Sent: Thursday, March 28, 2002 9:46 AM Subject: Re: OSPF NSSA [7:38881] The answer to the original question is that it is a bug: CSCdw67111 (OSPFv2:default-info-originate has incorrect metric type for NSSA). It isn't fixed until 12.2(10), which isn't out yet.

Re: OSPF NSSA [7:38881]
Steve, I think on p540 of Jeff Doyle, the reason that it has N1 metric type is because the RIP routes are redistributed into OSPF with metric type 1. Lee Steven A. Ridder wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... According to the example in Doyle's Vol 1. book, using the command no redis instead of default-metric creates the N1 stuff. It's on page 540, footnote 27. -- RFC 1149 Compliant. Get in my head: http://sar.dynu.com Chee Kin wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: OSPF NSSA [7:38881]
Hi Georg, I am using IOS12.1.7 and it allows me to issue this syntax: area area-id nssa default-information originate metric-type 1 On IOS 11.x, it only allows me to issue this: area area-id nssa default-information originate If I leave the metric-type 1 off, I will get *N2 for the default route. If I use default-information originate metric-type 1, I will still get the same result. Looks like I may need to get a copy of Jeff Doyle's book and do a bit of reading on the NSSA stuff. The results of my NSSA config is way different from what I have anticipated. Thanks for your input anyway. I will let you know if I discover anything new. Regards, cheekin - Original Message - From: Georg Pauwen To: Sent: Wednesday, March 20, 2002 11:36 PM Subject: RE: OSPF NSSA [7:38881] Hi Cheekin, AFAIK, the syntax for the area nssa is: area area-id nssa default-information-originate which will generate a type 7 default into the NSSA area (NSSA ABR or NSSA ASBR only). So I think the 'metric-type 1' might confuse it. What happens when you leave 'metric-type 1' off ? I think that a default route of type 1 will only show up in the routing table when you use the default-information-originate metric-type 1 in router config mode, e.g.: router ospf 1 default-information-originate metric-type 1 Hope this helps.

Re: OSPF NSSA [7:38881]
Hi, I just did this up in my lab and got the same results using the metric-type option. Always was a N2. I checked the 12.1 and 12.2 command reference for 'area nssa' and metric-type and metric aren't listed as options for this command in the docs. That might not mean anything though. I also set a metric and metric-type 1 with same result. 'debug ip ospf lsa-gen' shows a external LSA for 0.0.0.0 being created as a type 2. As George stated a regular default-info-originate w/metric works fine. But then these options shouldn't be available on the area nssa command if they don't work. Anyone pursue this with the TAC or Cisco yet to confirm if its a bug?? --- Chee Kin wrote: Hi Georg, I am using IOS12.1.7 and it allows me to issue this syntax: area area-id nssa default-information originate metric-type 1 On IOS 11.x, it only allows me to issue this: area area-id nssa default-information originate If I leave the metric-type 1 off, I will get *N2 for the default route.
