Configuring DVMRP

DVMRP is an advanced routing feature that must be enabled with a license key. If you have purchased an
advanced license key, and have enabled routing on the device, you must activate your license as described
in "Activating Licensed
purchase an advanced routing license, contact Enterasys Networks Sales.

Purpose

To enable and configure the Distance Vector Multicast Routing Protocol (DVMRP) on an interface.
DVMRP routes multicast traffic using a technique known as Reverse Path Forwarding. When a
router receives a packet, it floods the packet out of all paths except the one that leads back to the
packet's source. Doing so allows a data stream to reach all VLANs (possibly multiple times). If a
router is attached to a set of VLANs that do not want to receive from a particular multicast group,
the router can send a "prune" message back up the distribution tree to stop subsequent packets
from traveling where there are no members. DVMRP will periodically reflood in order to reach
any new hosts that want to receive from a particular group.
