Monitoring the IPsec Transport Interface Used to Secure DVMRP Tunnels
Purpose
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.
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 Data rx 0 0 0 0 Data tx 0 0 0 0 1 DVMRP tunnel found 1 tunnel was created static
