Configuring IP Routing
Configuring and Modifying DVMRP
Distance Vector Multicast Routing Protocol (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.
Configuring the DVMRP Global Configuration
Web Agent
Procedure To configure DVMRP globally using the Web Agent:
1. In the navigation pane, expand the Routing > IP > Configuration
folders, and then click Global Configuration. The IP Global
Configuration Web page is displayed in the content pane. See
Figure 12-15 .
2. Select Enable from the IP Multicast Forwarding field to enable IP
multicast globally.
3. In the navigation pane, expand the Routing > DVMRP folders, and then
click Global Configuration. The DVMRP Global Configuration Web
page is displayed in the content pane. See
Figure 12-17 .
