Device# show dmvpn Legend: Attrb --> S - Static, D - Dynamic, I - Incomplete N - NATed, L - Local, X - No Socket # Ent --> Number of NHRP entries with same NBMA peer ! The line below indicates that the sessions are being displayed for Tunnel1. ! Tunnel1 is acting as a spoke and is a peer with three other NBMA peers.

- IPSec - this indicates that the DMVPN session is down due to an IPSec error
