Globally Enabling and Disabling DVMRP
To globally enable DVMRP, enter the following command:
Router1(config)# router dvmrp
Syntax:
[no] router dvmrp
The behavior of the
[no] router dvmrp
command is as follows:
•
Entering a
router dvmrp
command to enable DVMRP does not require a software reload.
•
Entering a
no router dvmrp
command removes all configuration for PIM multicast on a Layer 3 Switch
(
router pim
level) only.
Globally Enabling or Disabling DVMRP without Deleting Multicast Configuration
As stated above enter
no router dvmrp
removed PIM configuration. If you want to disable or enable DVMRP
without removing PIM configuration, enter the following command:
FastIron SuperX Router(config)# router dvmrp
FastIron SuperX Router(config-pim-router)# disable-dvmrp
Syntax:
[no] disable-dvmrp
Use the [no] version of the command to re-enable DVMRP.
Enabling DVMRP on an Interface
After globally enabling DVMRP on a Layer 3 Switch, enable it on each interface that will support the protocol.
To enable DVMRP on Router 1 and interface 3, enter the following:
Router1(config)# router dvmrp
Router1(config-dvmrp-router)# int e 3
Router1(config-if-3)# ip dvmrp
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.
To modify the neighbor timeout value to 100, enter the following:
FastIron SuperX Router(config-dvmrp-router)# nbr 100
Syntax:
nbr-timeout <40-8000>
The default is 180 seconds.
