Hi All,
We have 2x 3750G L3 switches and I am trying to set them up to use EIGRP but for some reason it’s not working, I created 2 routed ports on each switch and I want to route vlan10 traffic to vlan20 to S2. I also enable EIGRP as the routing protocol but I still cannot ping between VLAN 10 and VLAN20 , here are the configs for both switches. What am I doing wrong? Any help would be much appreciated!!!

why did you set those interfaces as passive? your EIGRP neighborship is not coming up because of this. You want to remove those commands.

you need a network statement under EIGRP for the subnet used on the routed link between two switches

Hi Roman,
Thanks for the fast reply, I've done the following on both switches:
router eigrp 10
redistribute connected
passive-interface GigabitEthernet1/0/23
passive-interface GigabitEthernet1/0/24
network 192.168.10.0
network 192.168.20.0
network 192.168.1.0
network 192.168.2.0
no auto-summary
router eigrp 10
redistribute connected
passive-interface GigabitEthernet2/0/23
passive-interface GigabitEthernet2/0/24
network 192.168.10.0
network 192.168.20.0
network 192.168.1.0
network 192.168.2.0
no auto-summary
Still no luck, I can ping everything from both switches except the for vlan interfaces.

new adjancy is UP Thank you very much for you help!
passive interface command was a mistake, it will actually prevent hello packets and the EIGRP network flow to neighbors
interesting but still cannot ping VLAN 10/20 interfaces
