    Monitoring the IPsec Transport Interface Used to Secure DVMRP Tunnels


    Display information about a DVMRP tunnel or a list of DVMRP tunnels.

    If the tunnel is protected by IPsec, the show dvmrp tunnel detail command includes a line indicating the IPsec transport interface. The line is not shown for unsecured tunnels.


    To display information about a DVMRP tunnel:

    host1#show dvmrp tunnel detail
    DVMRP tunnel boston1 is up (tunnel is static)
    Tunnel operational configuration
      Tunnel name is 'boston1'
      Tunnel mtu is '10240'
      Tunnel source address is ''
      Tunnel destination address is ''
      Tunnel transport virtual router is vr1
      Tunnel up/down trap is enabled
      Tunnel server location is 4/0
      Tunnel secured by ipsec transport interface 1
      Tunnel administrative state is up
    Statistics    packets         octets          discards      errors
      Data rx     0               0               0             0

    1 DVMRP tunnel found 
    1 tunnel was created static
