Monitoring Dynamic DVMRP Tunnels
Purpose
Display information about dynamic DVMRP tunnels. You can specify the detail keyword to view detailed information about tunnels. You can specify the state keyword and the state of the tunnel (disabled, down, enabled, lower-down, not-present, up) to view the number of tunnels in a specific state. To view the state of a specific tunnel, specify a tunnel name. To view the number of tunnels associated with that IP address, specify an IP address. You can specify an IP address with the virtual-router keyword and the name of the virtual router to view the number of tunnels associated with an IP address on the virtual router.
Action
To display three dynamic DVMRP tunnels:
host1:vr11#show dvmrp tunnel DVMRP tunnel mvpn-dynamic-1 is Up DVMRP tunnel mvpn-dynamic-2 is Up DVMRP tunnel mvpn-dynamic-3 is Down
3 DVMRP tunnels found 3 tunnels were created dynamic
To display the detail of a dynamically created DVMRP tunnel for the data MDT application:
host1:vr11#show dvmrp tunnel detail mvpn-dynamic-1 DVMRP tunnel mvpn-dynamic-1 is Up tunnel is dynamic Application is MVPN Tunnel operational configuration Tunnel mtu is '5000' Tunnel source address is '1.1.1.1' Tunnel destination address is '2.2.2.2' Tunnel transport virtual router is vr1 Tunnel mdt is disabled Tunnel up/down trap is enabled Tunnel-server location is 4/0 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 dynamically
To display the detail of a dynamically created DVMRP tunnel for the Mobile IP application:
host1:vr12#show dvmrp tunnel detail mobileIp-dynamic-1 DVMRP tunnel mobileIp-dynamic-1 is Up tunnel is dynamic Application is Mobile-IP Tunnel operational configuration Tunnel mtu is '5000' Tunnel source address is '6.6.6.6' Tunnel destination address is '3.3.3.3' Tunnel transport virtual router is vr1 Tunnel mdt is disabled Tunnel checksum option is disabled Tunnel sequence number option is disabled Tunnel key is disabled Tunnel up/down trap is enabled Tunnel-server location is 6/0 Tunnel administrative state is Up Statistics packets octets discards errors Data rx 0 0 0 0 Data tx 0 0 0 0
To display a summary of information about DVMRP tunnels:
host1#show dvmrp tunnel summary Administrative status enabled disabled 1 0 Operational status up down not-present 1 0 0
Meaning
Table 1 lists the show dvmrp tunnel command output fields.
