Configuring DVMRP
Enabling DVMRP globally and on an interface
Suppose you want to initiate the use of desktop video for fellow users on a sprawling campus
network. All destination workstations have the appropriate hardware and software but the BigIron
RXes that connect the various buildings need to be configured to support DVMRP multicasts from
the designated video conference server as seen in
Figure 96 .
DVMRP is enabled on each of the BigIron RX devices, shown in Figure 96 , on which multicasts are
expected. You can enable DVMRP on each BigIron RX independently or remotely from one BigIron
RX by a Telnet connection. Follow the same steps for each router.
Globally enabling and disabling DVMRP
To globally enable DVMRP, enter the following command.
BigIron RX(config)# router dvmrp
BigIron RX(config)#
Syntax: [no] router dvmrp
•
Entering a router dvmrp command to enable DVMRP does not require a software reload.
•
Entering a no router dvmrp command removes all configuration for PIM multicast on a BigIron
RX (router pim level) only.
Globally enabling or disabling DVMRP without deleting multicast configuration
As stated above enter no router dvmrp removed PIM configuration. If you want to disable or enable
DVMRP without removing PIM configuration, enter the following command.
BigIron RX(config)# router dvmrp
BigIron RX(config-pim-router)# disable-dvmrp
Syntax: [no] disable-dvmrp
Use the [no] version of the command to re-enable DVMRP.
Enabling DVMRP on an interface
After globally enabling DVMRP on a BigIron RX, enable it on each interface that will support the
protocol.
To enable DVMRP on Router 1 and interface 3, enter the following.
Router1(config)# router dvmrp
Router1(config-dvmrp-router)# int e 3/1
Router1(config-if-e10000-3/1)# ip dvmrp
Modifying DVMRP global parameters
DVMRP global parameters come with preset values. The defaults work well in most networks, but
you can modify the following global parameters if you need to:
