19.6 DVMRP

DVMRP (Distance Vector Multicast Routing Protocol) is a protocol used for routing multicast
data within an autonomous system (AS). This DVMRP implementation is based on draft-ietf-
idmr-dvmrp-v3-10. DVMRP provides multicast forwarding capability to a layer 3 switch that
runs both the IPv4 protocol (with IP Multicast support) and the IGMP protocol. The DVMRP
metric is a hop count of 32.
IGMP is a protocol used for joining or leaving a multicast group. You must have IGMP
enabled when you enable DVMRP.
To open the DVMRP screen, right-click on a switch in the Device Panel list and click
Configuration > IP Configuration > DVMRP.
