Thanks for responding.

I can't ping from the 172.23.31.32/27 net

to the 10.90.153.0/24 net

Attached is a screen shot of the routing tables of one of the switches

Well, it seems that the 10.90.153.0 network is not in your eigrp routing table at all, meaning that anything destined for that network will use the static route you have applied (ip route 0.0.0.0 0.0.0.0 172.23.31.33). I'm not exactly sure what this route is doing... Is there more than the 2 devices stated in this network?

-Chris

There is a router attached to port 48 that

is the default gateway for the whole network.

I turned off auto-summarization on the switch named Test and it now shows the 172.23.31.32/27 net in it's routing table,

but when I did it on the switch E3, it did not pick up the 10.90.153.0/24 net.

?

Current configs and tables attached.

Thanks for your help,

Ric

Based on your EIGRP configuration, I can't see anything wrong. I DO see a problem with your static default route on Test though.

Neither "ip route 0.0.0.0 0.0.0.0 172.23.31.33" or "ip default-gateway 172.23.31.33" should be configured on Test because that is not a next hop address this router is familiar with.

Instead, I suggest that you enter the "default-information originate" or "redistribute static" command in EIGRP on your E3 router. This maaaay fix your issues.

-Chris

Oh, you should also check to see if Vlan 1 is even UP on Test. This route wont get advertised by EIGRP if the SVI is down, might want to check that out too if the previous solution doesn't do anything.

VLAN 1 is up on Test. I can connect a client as 10.90.153.x

and ping the E3 switch at 172.23.31.34, but no other IP's

on that 172.23.31.32/27 net.

I changed the default on Test as shown below and no luck.

There's something on the E3 switch that is not right.

I even tried making VLAN 1 passive on E3 and no luck.

Thanks, Ric

Its a strange situation which is happening. EIGRP is making a neighbor relationship as far as " Test " switch is concerned. What happens when you issue " show ip eigrp neighbor " on E3 switch. Do you see the test listed a neighbor.

Here are the two things that we can try:

1.Try changing the connection between the 2 switches to a vlan SVI instead of using the routed port.Let us check if the eigrp neighbor relationship comes up.

2.Try debugging thye rigrp relationship and attach the debugs.

On suggestion #1, do you mean connect them together without using the 192.168.1.0/30 net?

Thanks, Ric

He means:

Test#

int vlan 192

ip add 192.168.1.1 255.255.255.252

no shut

int gi0/17

switchport mode access

switchport access vlan 192

E3#

int vlan 192

ip add 192.168.1.2 255.255.255.252

no shut

int gi0/17

switchport mode access

switchport access vlan 192

At least I think he means that... Give it a shot and get back to us.

-Chris

Yeah. I meant the same as posted by Chris. The output in your earlier post shows that E has a succesful naighbor relationship with test.Please paste the output of " show EIGRP topo " from the E3.

Also let me know the IOS version that your are running on 3560's.

E3 is not picking up the 10.90.153.0/24 net in it's routing table. Diagram is attached.

Thanks very much, Ric

Did you at any point had an interface on router E3 configured with an IP from 10.90.153.0/24 subnet?
