Can i see config

juniorboniface1 · ‎11-27-2023

Please see the attached.

It is the config for the branch location with the error

Many thanks

MHM Cisco World · ‎11-28-2023

Your config is correct except

Try first Use interface not use ip in tunnel source and monitor the eigrp is stable or not

Try use tunnel key fod both tunnels (you need to add tunnel key in other router).

If above not work

Share

Show ip eigrp neighbor

Thanks

Hello ,

Thank you for your feedback.

The above did not work. Could it be a result of the cisco 1000 series switch ?

Also, the sh eigrp ne

MHM Cisco World · ‎11-28-2023

Show ip eigrp neighbor detail

I need to see this

MHM Cisco World · ‎11-28-2023

From output the hello is send receive between peer since it appear as neighbor' q-count non zero that good meaning the update also send and receive ack for it.

Uptime is small so I think it is issue of ISP not your issue.
