A couple weeks ago I experimented with multi-area OSPF and was confused by the output of my "show ip ospf database" command. I didn't like the way some of the "Link ID's" were network ID's and some were router ID's.
Everyone here was very helpful and patient with me (thanks) and I think I have made my peace with the simple (but for my purposes, still illogical) fact that only multiaccess networks will have their network ID's appear as Link ID's within their own area. Because intra-area network ID's come from Type 2 LSA's. And only DR's, which of course are found only on multiaccess networks, get to create Type 2 LSA's.
OK fine; so that's how it is.
But is anyone else out there at least FRUSTRATED, like I am, by the fact that that's how it is? Point-to-point networks get to have their network ID's appear in other areas as summary (Type 3) LSA's!! Why I ask you WHY should this convenient type of listing be denied to same-area routers?!?!?
Why I ask you WHY shouldn't a point-to-point router be allowed to create a Type 2 LSA for its perfectly respectable point-to-point network?
ssssiiighhh... like I said, I know I have to make peace with this; but I'll get there sooner if I know there's someone out there who agrees with me.
Or who can otherwise explain the reasoning behind the rules as they are.
