EIGRP Not working

markulous

So I'm going through Jeremy's CBT Nuggets videos for the CCNA. Just got the EIGRP config. Seems like it is super easy to setup. All he did was go into global config mode, go to rou eigrp 1, and advertise the network on that router and EIGRP was working fine for him in GNS3. I did that on both routers, yet when I go to sh ip eigrp neigh it doesn't show anything. Everything on my network pings each other just fine. I attached my topo.

no!all!

Does a sh ip route give you any routes known by EIGRP? Have you tried any debugging?

What's the config look like? Interface and EIGRP.

Heero

Maybe provide configs?

I never really used the PT-Cloud so I don't know it's setup but maybe it does not support eigrp?
Is the layer 3 switch routing the vlans? What are you trying to accomplish with the eigrp?

ip routing on L3 switch?

It only shows connected routes and a static route I put in for 0.0.0.0. I forgot to mention that.

Hmm...now that I did the debug, for some reason ROUTER0 is not sending Hellos to SWOUTER0, only to the serial interface.

Yes that is enabled. It routes packets through vlans just fine.

Dieg0M

send configs or we will be guessing all day

Doesn't look like it wants to communicate through Gig 0/0 so SWOUTER0 is sending hello messages there and ROUTER0 is just ignoring them and not sending anything back. I disabled passive-interface on everything and Gig 0/0 specifcally but no change.

That is not what I asked for. Please post the config.

ROUTER0:
router eigrp 1
network 10.0.0.0

In IGP's the network command does not advertise a network but indicates at the router what interface matching that subnet should be using the IGP (and advertising hello's for neighborship)

I have no idea if it does or not. I was just using that to setup frame relay.

Yes, the L3 switch is routing the Vlans.

I am just trying to experiment with it so it'll advertise routes. I'm just following along with CBT Nuggets anytime they configure something.

That just formed the adjacency. I was advertising that route on SWOUTER0, why do I have to advertise it again on ROUTER0? Or am I misinterpreting the command?

Ah...ok so every time I do the network command on one interface, I need to do it on the corresponding interface to form the adjacency. So I see this working best in a large environment where a lot of routes have to be summarized.

When you use EIGRP, first step is to use after the Router eigrp XXX command is "no auto summary" command. If not you can have 2 branch routers advertising the same routes because summarization is on by default. You should also get in the habit of using the subnet mask for your route advertisements.
