RE: EIGRP neighbor relation over a tunnel interface

I can ping the tunnel interface of R1 from R2 sourced from the tunnel on R2,
R2 can see the Hello from R1, but now hello received on R1 from R2, even the
tunnel network is participating under both of the routers.

The tunnel source and destination is configured statically on both routers.

Hi Amin,

You haven't quite given enough information to isolate a response but these
are some of the troubleshooting steps I would consider using to help isolate
the problem

From R1 can you ping the R2 Tunnel0 interface?
If not, have you tried specifying the tunnel source on R1 Tunnel40 to use
10.10.10.102 just to be certain?

I am assuming that you're using the same EIGRP AS number and the metric
weights are the same on each router.
How are you learning the tunnel source/destinations? Are you using EIGRP as
well? Perhaps you are having issues with recursive routing and need to look
in that area to resolve the issue.

Cheers,
Adam

Hi experts,

I have a problem establishing eigrp relation over a tunnel , even the tunnel
is up and participating under the eigrp process, but R2 can see R1, while R1
can't see R2?? Any advice

R1

interface Tunnel40

 ip address 192.168.230.105 255.255.255.252

tunnel source Serial0/1/0:1

 tunnel destination 192.168.71.2

R2

interface Tunnel0

ip address 192.168.230.106 255.255.255.252

tunnel source 192.168.71.2

 tunnel destination 10.10.10.102
