  3. Hi Mohammad,

    With DMVPN phase 1, it is straight-forward. All traffic (including spoke-to-spoke traffic) always goes through the hub.

  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.
