4.5.6.1.6 Configuring DVMRP
Distance Vector Multicast Routing Protocol is used to route multicast traffic to nodes which have
requested a specific multicast service via IGMP. (See “6.4.4 DVMRP Routing Protocol”) To configure
DVMRP, you must specify the routing metric, probe interval, and neighbor router timeout.
Parameter Default Description
Metrics 1 hop This value is used to select the best reverse path to networks that are
connected directly to an interface on this switch.
Range: 1-31 hops
Probe Interval 10 seconds The interval between sending neighbor probe messages to the multicast
group address for all DVMRP routers.
Range: 5-30 seconds
Neighbor
Timeout
35 seconds The interval to wait without hearing from a DVMRP neighbor before
declaring it dead. This is used for timing out routes, and for setting the
children and leaf flags.
Range: 10-8000 seconds
NOTE: IGMP is automatically enabled/disabled along with DVMRP. (See “6.4.2 IGMP Protocol”.)
