Hi,
Did you experience with me same situation before you apply the redi
connected?
If I don't apply the redi connected, is it impossible to see the
172.25.0.1?
You told me the reason may be ios bug. But I don't think so.
This is basic routing problem. I think Cisco can control this basic
function.
However 172.25.0.1/24 should be updated by neighbor. And all other networks
are updated normally. Only 172.25.0.0/24 is not.
R3 can see this network. But R1 can't as you know....
Redi conn may be good solution. But Does this situation cannot be solved by
just Eigrp routing not using a redi conn?
Thanks for your sincere help..
