Modifying DVMRP Global Parameters

DVMRP global parameters come with preset values. The defaults work well in most networks, but you can modify
the following global parameters if you need to:
• Neighbor timeout
• Route expire time
• Route discard time
• Prune age
• Graft retransmit time
• Probe interval
• Report interval
• Trigger interval
• Default route
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.
USING THE CLI
To modify the neighbor timeout value to 100, enter the following:
BigIron(config-dvmrp-router)# nbr 100
Syntax: nbr-timeout <40-8000>
The default is 180 seconds.
