Help Required on DMVPN

Hello Haider,

We would need to see your configurations and possibly also the state of routing tables before activating any tunnel, after activating the first tunnel and after activating the second tunnel. My first suspicion is that you have some kind of a routing loop or a recursive routing (a tunnel endpoint learned through the tunnel itself).

Best regards,

Peter
