Configuring IP Routing
Configuring and Modifying Distance Vector Multicast
Routing Protocol (DVMRP)
DVMRP uses IP packets with protocol type 2 (IGMP) to exchange
routing datagrams. DVMRP enables multicast routers to exchange
distance vector updates that contain multicast flow lists and their
corresponding cost metrics. DVMRP may use tunneling between
pairs of DVMRP routers when traffic must pass through one or more
intermediary routers or gateways that do not implement
DVMRP.This implementation adheres to the specification for
DVMRP V3.
You can configure DVMRP Globally using either the Web Agent or
the CLI.
* Note: When processing heavy traffic, the switch may lose a
small number of DVMRP neighbor-to-neighbor probe
messages. The loss of these messages may cause
multicast routing to become unstable.

Using the Web
Agent
To configure DVMRP globally using the Web Agent:
1. Select Global Configuration from the Routing > IP >
Configuration group on the Web Agent window. The IP
Global Configuration dialog box opens (Figure 6-41).
2. Select Enable from the IP Multicast Forwarding field
pull-down menu to enable IP multicast globally.
3. Select Global Configuration from the Routing > DVMRP
group on the Web Agent window. The DVMRP Global
Configuration dialog box opens (Figure 9-19).
