Modifying Route Expires Time
The Route Expire Time defines how long a route is considered valid in the absence of the next route update.
Possible values are from 20 – 4000 seconds. The default value is 200 seconds.
To modify the route expire setting to 50, enter the following:
FastIron SuperX Router(config-dvmrp-router)# route-expire-timeout 50
Syntax: route-expire-timeout <20-4000>
Modifying Route Discard Time
The Route Discard Time defines the period of time before a route is deleted. Possible values are from 40 – 8000
seconds. The default value is 340 seconds.
To modify the route discard setting to 150, enter the following:
FastIron SuperX Router(config-dvmrp-router)# route-discard-timeout 150
Syntax: route-discard-timeout <40-8000>
Modifying Prune Age
The Prune Age defines how long a prune state will remain in effect for a source-routed multicast tree. After the
prune age period expires, flooding will resume. Possible values are from 20 – 3600 seconds. The default value is
180 seconds.
To modify the prune age setting to 150, enter the following:
FastIron SuperX Router(config-dvmrp-router)# prune 25
Syntax: prune-age <20-3600>
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:
FastIron SuperX Router(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:
FastIron SuperX Router(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:
FastIron SuperX Router(config-dvmrp-router)# report 90
Syntax: report-interval <10-2000>
