    Action

    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 '0.0.0.0'
      Tunnel destination address is '0.0.0.0'
      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
