Activating DVMRP on an Interface
By default, DVMRP is not activated on an interface. Configuring any DVMRP parameter
on an interface automatically activates DVMRP on that interface. You can also activate
DVMRP on an interface and use the default parameters.
ip dvmrp
■
Use to activate DVMRP on an interface.
■
This command automatically creates and enables DVMRP processing on the
current VR.
■
Issuing this command identifies this interface as one that DVMRP owns.
■
Example
host1:boston(config-if)# ip dvmrp
■
Use the no version to remove DVMRP from an interface.
■
See ip dvmrp.
Configuring DVMRP Limits
You can configure DVMRP and IGMP on the same interface. If you configure DVMRP
and IGMP on an interface, the router determines that DVMRP owns the interface.
NOTE: You cannot configure DVMRP and PIM on the same interface.
When you have enabled DVMRP processing on a VR, you can configure the following
settings for that VR:
■
The number of routes that the VR advertises on each interface.
■
A maximum number of DVMRP routes at which the router generates a system
log warning message and an SNMP trap.
ip dvmrp route-hog-notification
■
Use to set the number of DVRMP routes that the router can record before it
generates a system log warning message.
■
The warning alerts you so you can identify routers that are injecting large numbers
of routes into the MBone.
■
Example
host1:boston(config)# ip dvmrp route-hog-notification 5000
■
Use the no version to restore the default value, 10,000 routes.
■
See ip dvmrp route-hog-notification.
