I am trying to enable EIGRP on both my 2600 and 3640, but I keep getting :
IP-EIGRP(Default-IP-Routing-Table:1): Neighbor 192.168.2.1 not on common subnet for Ethernet0/0
on the 2600....
Help please:

Hi,
no it won't form a neighbour relationship.

Hi,
As you mentioned there is IP address on the point to point link are not in same subnet.Change the subnet IP address either on e0/0 OR f0/1.
interface Ethernet0/0
ip address 192.168.3.1 255.255.255.0 <<<<<
half-duplex
interface FastEthernet0/1
ip address 192.168.2.1 255.255.255.0 <<<

So EIGRP does not work on two different subnets?
