3650 routed port sending eigrp advertisements from SVI
My production setup involves a 3560 connected to a 4506 via routed fiber ports on both devices. The 4506 is throwing EIGRP neighbor not on common subnet from that interface. The address that is showing is from an SVI on the 3560. I was able to reproduce this at my desk with 2 3560s. Relevant config snippets are below. The switches are connected with sx optics in G0/1. I can't reproduce this when using a copper crossover between two Fe ports. The switches are running c3560-ipservicesk9-mz.122-53.SE Any ideas? This has got me stumped.
SW 1: interface GigabitEthernet0/1 no switchport ip address 10.0.0.1 255.255.255.252 ! interface Vlan5 ip address 10.0.1.1 255.255.255.0 ! router eigrp 1 network 10.0.0.0
Geting this error on SW1: EIGRP-IPv4(1): Neighbor 10.0.2.1 not on common subnet for GigabitEthernet0/1
SW2: interface GigabitEthernet0/1 no switchport ip address 10.0.0.2 255.255.255.252 ! interface Vlan6 ip address 10.0.2.1 255.255.255.0 ! router eigrp 1 network 10.0.0.0
Getting this error on SW2: EIGRP-IPv4(1): Neighbor 10.0.1.1 not on common subnet for GigabitEthernet0/1

Verify ip classless is configured also you should passive interface any interfaces including SVI's that are not connecting links to other network routing devices.. See if the messages are still there after you passive interface the SVI's . I have seen that before and I can't remember what we did to fix it .

I am going to design and build an LAN network under a tunnel underground with long distance between the switches.
I will have 2 Catalyst switches and 8 Industrial IE3000, and they will be connected with fiber.
