Modifying neighbor timeout
The neighbor timeout specifies the period of time that a router will wait before it defines an
attached DVMRP neighbor router as down. Possible values are 40 – 8000 seconds. The default
value is 180 seconds.
To modify the neighbor timeout value to 100, enter the following.
BigIron RX(config-dvmrp-router)# nbr 100
Syntax: nbr-timeout <40-8000>
The default is 180 seconds.
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.
BigIron RX(config-dvmrp-router)# route-expire-time 50
Syntax: route-expire-time <value>
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.
BigIron RX(config-dvmrp-router)# route-discard-time 150
Syntax: route-discard-time <value>
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.
