[no] ip dvmrp
Enable DVMRP; the “no ip dvmrp enable”
command disables DVMRP (required)
2. Configure connectivity with CISCO routers/switches
CISCO does not really implemented DVMRP, but provides connectivity with DVMRP. As
CISCO routers/switches send report packet but not probe packets, neighbor timeout issue
should be addressed in establish connectivity with CISCO routers/switches. The following
command makes a DSRS-5950 switch to decide the timeout of a neighbor by report
packet intervals.
Command Explanation
Interface Mode
[no] ip dvmrp cisco-compatible
<A.B.C.D>
Enable connectivity with CISCO neighbor A,
B, C, D; the “no ip dvmrp cisco-compatible”
command disables connectivity with CISCO
neighbors.
3. Configure DVMRP sub-parameters
(1) Configuring DVMRP interface parameters.
a. Configure metric value for DVMRP report packet
b. Configuring DVMRP neighbor timeout time
Command Explanation
Interface Mode
ip dvmrp metric <metric_val>
no ip dvmrp metric
Set interval for sending DVMRP report
packets in the interface; the “no ip dvmrp
metric” command restores the default setting.
ip dvmrp nbr-timeout <time_val >
no ip dvmrp nbr-timeout
Set timeout interval for DVMRP neighbors in
the interface; the “no ip dvmrp nbr-timeout”
command restores the default setting.
(2) Configuring DVMRP global parameters.
a. Configure transmission interval of graft packets in DVMRP
b. Configure transmission interval of probe packets in DVMRP
c. Configure transmission interval of report packets in DVMRP
Command Explanation
Global Mode
ip dvmrp graft-interval <time_val>
no ip dvmrp graft-interval
Set the interval for sending DVMRP graft
messages; the “no ip dvmrp graft-interval”
command restores the default setting.
ip dvmrp probe-interval
<time_val>
no ip dvmrp probe -interval
Set the interval for sending DVMRP probe
messages; the “no ip dvmrp probe interval”
command restores the default setting.
