Enable DVMRP globally

Use the Globals tab to set DVMRP global parameters.

To enable DVMRP globally:

Choose IP Routing > DVMRP > Globals.

The DVMRP dialog box opens, and the Globals tab is displayed.

Select the Enable check box.

Click Apply.


Field	Description
Enable	Enables (true) or disables (false) DRMRP on the routing switch. DVMRP must be globally enabled before port or VLAN DVMRP can be enabled.
UpdateInterval	Periodically each multicast router advertises routing information on each DVMRP interface, using the DVMRP export message. You can specify the time interval (in seconds) between DMVRP updates. The range is from 10 to 2000 with a default of 60.
TriggeredUpdateInterval	Triggered updates are sent when routing information changes. This value is the amount of time (in seconds) between triggered update messages. The range is from 5 to 1000 with a default value of 5.
LeafTimeOut	When DVMRP advertises a route on an interface, it waits a period of time for a DVMRP neighbor to respond positively. If no neighbor responds in the given time, the router considers the network attached to the interface to be a leaf network. The leaf timer allows you to specify how long (in seconds) the router waits for a response from a neighbor. The range is from 25 to 4000 with a default value of 200.
NbrTimeOut	The neighbor report timer specifies how long (in seconds) the router waits to receive a report from a neighbor before considering the connection inactive. The range is from 35 to 8000 with a default of 140.
NbrProbeInterval	Specifies how often the DVMRP router sends probe messages on its interfaces. The range is 5 to 30 seconds with a default of 10.
VersionString	The router's DVMRP version information.
GenerationId	Used by neighboring routers to detect whether a reset or disable/enable DVMRP action has occurred to the switch or to a particular interface. If so, the router should resend the entire multicast routing table to its neighbor immediately instead of waiting for the next scheduled update.
NumRoutes	The number of entries in the routing table. This information can be used to monitor the routing table size to detect illegal advertisements of multicast routes.
ReachableRoutes	The number of entries in the routing table with noninfinite metrics. This number can be used to detect network partitions by observing the ratio of reachable routes to total routes.
