Configuring DVMRP
Before configuring DVMRP, consider the following:
•
DVMRP requires that IP Multicast Switching (IPMS) is enabled. IPMS is automatically enabled when
a multicast routing protocol (either PIM or DVMRP) is enabled globally and on an interface
and
when
the operational status of the interface is up. However, if you wish to manually enable IPMS on the
switch, use the
ip multicast admin-state
command.
•
You can configure DVMRP parameters when the protocol is not running
as long as DVMRP is loaded
into memory
(see
“Loading DVMRP into Memory”
below).
•
The DVMRP parameters will
not
take effect until the protocol is enabled globally
and
on specific IP
interfaces.
Enabling DVMRP on the Switch
Before running DVMRP, you must enable the protocol by completing the following steps:
•
Loading DVMRP into memory
•
Enabling DVMRP on desired IP interfaces
•
Enabling DVMRP globally on the switch
Note.
Once loaded and enabled, DVMRP is typically ready to use because its factory default values are
appropriate for the majority of installations. Note, however, if neighbors in the DVMRP domain have
difficulty handling large initial bursts of traffic, it is recommended that the subordinate neighbor status is
changed to false. For more information on the subordinate neighbor status, refer to the
ip dvmrp subord-
default
command in the
OmniSwitch CLI Reference Guide
.
For information on completing these steps, refer to the sections below.
Loading DVMRP into Memory
You must load DVMRP into memory before you can begin configuring the protocol on the switch. If
DVMRP is not loaded and you enter a configuration command, the following message displays:
ERROR: The specified application is not loaded
To dynamically load DVMRP into memory, enter the following command:
-> ip load dvmrp
