updating report message for a route from the neighbor of the route is
received in the specified interval, then the route is considered to be invalid.
This interval configured must be no greater than the timeout interval for the
route.
Example: Set the interval for sending DVMRP route report messages to 100s.
Switch (Config)#ip dvmrp report-interval 100
Command: ip dvmrp route-timeout <time_val>
no ip dvmrp route-timeout
Function: Set timeout interval for a DVMRP route; the “no ip dvmrp route-timeout”
command restores the default setting.
Parameter: < time_val> is the time to timeout a route, the valid range is 20 to 1400s.
Default: The default timeout setting for DVMRP routes is 140 seconds.
Command mode: Global Mode
Usage Guide: If no updating report message for a route from the neighbor of the route is
received in the specified interval, then the route is considered to be invalid.
This timeout interval must be greater than that for sending report messages.
Example: Configure the DVMRP route timeout interval to 100s.
Switch (Config)#ip dvmrp route-timeout 100
Command: ip dvmrp tunnel <A.B.C.D> [metric <metric_val>]
no ip dvmrp tunnel <A.B.C.D>
Function: Configure tunneling to neighbor A, B, C, D; the “no ip dvmrp tunnel”
command removes the tunnel to neighbor A, B, C, D.
Parameter: < A.B.C.D> is the IP addresses of remote neighbors; <metric_val> is the
metric value for the tunnelling interface, ranging from 1 to 32.
Default: DVMRP tunneling is disabled by default, the default value for <metric_val> is 1.
Command mode: Interface Mode
Usage Guide: Since not all switches support multicast, DVMRP provide support for
tunneling multicast information. Tunneling is a method used between
DVMRP switches separated by non-multicast routing switch(es). The tunnel
acts as the virtual network between two DVMRP switches. The multicast
packet is encapsulated in a unicast packet and destined to a
