dt,

Send relevant configs and maybe a show ip eigrp neighbors and sh ip route.

This appears when there are routers with interfaces on the same brodcast
domain but, have different ip subnets configured. A neighbor relationship
cannot be established this way, so I'm curious to see if/how the routing
tables are complete.

Subject: Eigrp - Nei not on common subnet

Hi group,

I have the following topology:

R2 s0.24 p2p-------- R4
       s0.123 p2m---R1
                        \
                          \ R3

R1 & R3 complain that R4 is not on a common subnet and
R4 complains that R1 and R3 are not on a common subnet. Both complaints are
true, the routing tables are fine on all routers and all pings between
routers
are successful. I also disabled split-horizon on s0.123, s0.24, and on s0
itself, but all 3 routers still complain.

Is this a problem from a lab point of view?

Thanks in advance, dt
