eigrp trouble

[Veance]

Hey 

I connected two 3560 cisco-switches through their gig0/1 port. Wanted to use eigrp to make the routing connection work.

But when I do a 'show ip route eigrp' command , nothing comes up. In 'show ip route' I only see C's and no D's.  

 

I will display the most important commands I made :

ip routing

int gig0/1 

no sw

ip address 192.168.0.3 255.255.255.0 ( the other switch I used 192.168.0.2)

router eigrp 1 (in both switches)

network 192.168.0.0 0.0.0.255

network 172.20.0.0 0.0.0.255 (in the other switch it was 172.30.0.0)

got the message of a neighbor that is up.

I used 'debug eigrp packets' and 'hello'packets were sent and received by the opposite port.

So I really don't know what's wrong. I first noticed because I couldn't ping from one side of switch MLS1 to the other side of switch MLS2.

vlan 10

name R&D

int vlan 10

ip address 172.20.10.1 255.255.255.0

and then in some cases I assigned a vlan to an interface like:

int fa0/1

sw mode access

sw access vlan 10

on both switches my gig0/1 are no switchports

@MHM Cisco World I don't think this will work. The OP has a L3 link between the devices. They cannot have the same subnets on the devices. Unless they are connected through L2 with another connection (i.e they are Distribution type switches that connect the Access layer)

You can't have the same subnet on both switches but assuming you don't change your EIGRP network statement to - 

172.20.0.0 0.0.255.255

I used 172.20.0.0 0.0.0.255 not 0.0.255.255

[David Ruess]

Is the same network subnet on both L3 switches? If that's the case then no you cannot. That's a discontiguos network.

In other words is the 172.20.0.0 and 172.30.0.0 network on both switches? You cannot have the same network separated by another L3 network (The L3 link between the 2 separates them)

Can you do a "show ip interface brief" on both devices?

I now did shut down the vlans that were only used in the other switch.

[MHM Cisco World]

Did you change the routing network statement as per my earlier message as well as @Jon Marshall ?

Make sure to delete your other one as well.
