  3. Hi Wandjlaye,

    If you are using 12.2, I can highly recommend to try this on IOS 15.

    12.2 is quite old and there have been quite some changes to DMVPN.

  5. Hi Abdus,

    This message:

    %ADJ-5-PARENT: Midchain parent maintenance for IP midchain out of Tunnel0

    Is usually a recursive routing issue. Your router is probably learning the NBMA address through the tunnel interface, which is why it collapses.
