RE: EIGRP Flapping using DMVPN/GRE.

This could indicate a design issue. Ensure that the recursion towards the "true" tunnel endpoints are via the actual interface rather than the logical tunnels.

Feel free to show configs. The same rules apply as with normal tunnels and tunnel recursion issues are fairly common.

Subject: EIGRP Flapping using DMVPN/GRE.

Does anyone know why EIGRP starts flapping when it is used with DMVPN/ GRE?

It is so annoying and painful. I have to remove the tunn interface and paste it back in. It works for a while and then drops again.

Is there a bug issue?

Thanks in advance.
