Configuring DVMRP

Modifying graft retransmit time
The Graft Retransmit Time defines the initial period of time that a router sending a graft message
will wait for a graft acknowledgement from an upstream router before re-transmitting that
message.
Subsequent retransmissions are sent at an interval twice that of the preceding interval. Possible
values are from
5 – 3600 seconds. The default value is 10 seconds.
To modify the setting for graft retransmit time to 120, enter the following.
BigIron RX(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’s 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 following.
BigIron RX(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
following.
BigIron RX(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 following.
BigIron RX(config-dvmrp-router)# trigger-interval 20
Syntax: trigger-interval <5-30>
Modifying default route
This defines the default gateway for IP multicast routing.
To define the default gateway for DVMRP, enter the following.
