Configuring DVMRP
1
DVMRP is enabled on each of the Brocade devices, shown in Figure 13 , on which multicasts are
expected. You can enable DVMRP on each Brocade device independently or remotely from one
Brocade device by a Telnet connection. Follow the same steps for each router.
Globally enabling and disabling DVMRP
To globally enable DVMRP, enter the following command.
Brocade(config)# router dvmrp
Brocade(config-dvmrp-router)#
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 DVMRP configurations on a Brocade device
(router dvmrp level) only.
Enabling DVMRP for a specified VRF
To enable DVMRP for the VRF named “blue”, use the following commands.
Brocade(config)# router dvmrp vrf blue
Syntax: [no] router dvmrp [vrf vrf-name ]
The vrf parameter allows you to configure DVMRP on the virtual routing instance (VRF) specified by
the vrf-name variable. All DVMRP parameters available for the default router instance are
configurable for a VRF-based DVMRP instance:
• Entering a router dvmrp vrf command to enable DVMRP does not require a software reload.
• Entering a no router dvmrp vrf command removes the DVMRP configuration from the specified
VRF only.
Enabling DVMRP on an interface
After globally enabling DVMRP on a Brocade device, enable it on each interface that will support
the protocol.
To enable DVMRP on Router 1 and interface 3, enter the following.
Brocade(config)# int e 3/1
Brocade(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:
• Neighbor timeout
• Route expire time
• Route discard time
• Prune age
• Graft retransmit time
• Probe interval
