DVMRP configuration on the Layer 3 switch and interface
To modify the setting for graft retransmit time to 120, enter the graft <num> command.
Brocade(config-dvmrp-router)#graft 120
Syntax: graft-retransmit-time <5-3600>
Modifying Probe Interval
The Probe Interval defines how often neighbor probe messages are sent to the
ALL-DVMRP-ROUTERS IP multicast group address. A router probe message lists those neighbor
DVMRP routers from which it has received probes. Possible values are from 5 – 30 seconds. The
default value is 10 seconds.
To modify the probe interval setting to 10, enter the probe <num> command.
Brocade(config-dvmrp-router)#probe 10
Syntax: probe-interval <5-30>
Modifying Report Interval
The Report Interval defines how often routers propagate their complete routing tables to other
neighbor DVMRP routers. Possible values are from 10 – 2000 seconds. The default value is 60
seconds.
To support propagation of DVMRP routing information to the network every 90 seconds, enter the
report <num> command.
Brocade(config-dvmrp-router)#report 90
Syntax: report-interval <10-2000>
Modifying Trigger Interval
The Trigger Interval defines how often trigger updates, which reflect changes in the network
topology, are sent. Example changes in a network topology include router up or down or changes in
the metric. Possible values are from 5 – 30 seconds. The default value is 5 seconds.
To support the sending of trigger updates every 20 seconds, enter the trigger-interval <num>
command.
Brocade(config-dvmrp-router)#trigger-interval 20
Syntax: trigger-interval <5-30>
Modifying default route
To define the default gateway for DVMRP, enter the following command.
Brocade(config-dvmrp-router)#default-gateway 192.35.4.1
Syntax: default-gateway <ip-addr>
