This chapter explains how to use commands to activate the Distance Vector Multicast Routing
Protocol (DVMRP) on the Switch.
15.1 DVMRP Overview
DVMRP (Distance Vector Multicast Routing Protocol) is a protocol used for routing multicast
data. DVMRP is used when a router receives multicast traffic and it wants to find out if other
multicast routers it is connected to need to receive the data. DVMRP sends the data to all
attached routers and waits for a reply. Routers which do not need to receive the data (do not
have multicast group member connected) return a "prune" message, which stops further
multicast traffic for that group from reaching the router.
15.2 Command Summary
The following section lists the commands for this feature.

DVMRP Commands

DESCRIPTION
Displays DVMRP group information.
Displays DVMRP interface information.
Displays DVMRP neighbor information.
Displays the DVMRP prune information.
Displays the DVMRP routes.
Displays DVMRP settings.
Enables and enters the DVMRP
configuration mode.
