Re: routing protocols over a serial link
Hmm... off the top of my head the only reason for that behavior that I can think of is a passive-interface statement in your eigrp config, which you'd probably notice. g Perhaps posting the configs is a good idea. John Hey again, I've run into a wall here trying to configure a small test lab. The problem is, In my network of three routers, No routing protocol will traverse one serial link. The serial link in question is up/up and ip traffic will pass across it. static routes work, dynamic routes aren't ever learned. The serial interfaces are all frame relay and are tested fully for ip functionality. All 3 routers have 2 serial interfaces apeice. They are linked in a triangle mesh on separate subnets for each link. They are running encapsulation frame-relay, with no keepalives. subinterfaces are point-to-point. On both the offending routers a show ip eigrp interfaces return showing just the ethernet ports of the routers as the only interfaces used in the routing process. Im just wondering if there is something crucial that I am totally missing here. If required I will paste out the configs in another email. I just don't like to write long emails with all the details if I don't have to. Sorry if I leave some holes. Any advice would be appreciated.

Re: routing protocols over a serial link
In EIGRP, the network statement specifies which interfaces are going to participate in the routing process. So, for every separate major network on the router, you need a different network statement. For example, on Router eo1 the only interface that will run EIGRP is e0. To have EIGRP run on all interfaces on that router, add "network 10.0.0.0". Do that for the necessary networks on each router and you should be good to go!

Re: routing protocols over a serial link
Luckily, the network command works similarly for both EIGRP and OSPF: they specify which interfaces are participating in the routing process. However, with OSPF I've noticed that if there is an interface that I don't want to run OSPF on, I still have to have a network statement for it or other routers won't be able to see that network. To stop the updates, I just add a passive interface command. This goes against what I understood about the network command in OSPF. In this case, it is also acting to specify which networks I want to advertise, and I thought it didn't act that way. Perhaps someone else will clear that up for us. Now, with BGP, the network statement definitely specifies which networks to advertise and has nothing to do with your interface IP addresses. But that's another story... g John Ya know, that fixed it right up. For some reason I was thinking it would cause troubles if I advertised the same network out but now that I read into it, thats not the context at all.
