Dear All,

i need help in configuring DMVPN for hub and spokes with two tunnels and two IPSec profiles. I hve configured both tunnels with IPSec on each site i.e Main office and branch office. When i enable firest tunnel with IPSec profile it working fine but whenever i enable second tunnel with IPSec branch office get down and ttl expired message occurs and on mean time Main office didn't get routes from Branch office. I am using EIGRP and AES encryption.

Kindly help me out on subject matter.

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
