Hi list,
I'm trying to figure out how bird distinguishes between imported routes that are shown as "external" route directly under the router's id (in "show ospf state") and those listed under the "other ASBRs" header. I have different boxes showing different behavior. I just can't seem to pinpoint the reason for a route show up under the "other ASBRs" header.
If current router does not have router LSA for that ASBR then its routes are listed under "other ASBRs" header. These are usually ASBRs from non-adjacent areas.
I'm afraid my lack of in-depth OSPF terminology is failing me here a bit, as I can't make much from what you just said. The routers listed as "other ASBRs" are listed under "area 0.0.0.0" as well. With stubnets listed in area 0.0.0.0, and externals listed as under other ASBRs. This happens for 2 (unrelated) routers in my networks. I have several other routers in my network where the stubnets and externals are listed just fine directly in the "area 0.0.0.0" block. Some additional info: I have a single area (only 0.0.0.0) setup consisting of about 16 routers and about 200 routes. The routes I'm trying to get into OSPF "cleanly" are 'manually' configured static routes (they are installed by heartbeat during a failover). Playing with stuff like "proto kernel" and "proto static" in order to get them picked up properly hasn't given me the desired results yet. The annoying part here is that I appear to have different behavior on various nodes, and I just can't spot the differences that cause that. Regards, Ruben Laban
