For information about modules that support DVMRP on the E120 and E320 Broadband
Services Routers:
•
See E120 and E320 Module Guide, Table 1, Modules and IOAs for detailed module
specifications.
•
See E120 and E320 Module Guide, Appendix A, IOA Protocol Support for information
about the modules that support DVMRP.

Before You Begin
You can configure multicasting on IPv4 and IPv6 interfaces.
For information about configuring IP interfaces, see Configuring IP in the JunosE IP, IPv6,
and IGP Configuration Guide. For information about configuring IPv6 interfaces, see
Configuring IPv6 in the JunosE IP, IPv6, and IGP Configuration Guide.
For information about configuring multicast on IPv6 interfaces, see “Configuring IPv6
Multicast” on page 141.
Enabling DVMRP on a VR
By default, DVMRP is enabled on the router. To enable DVMRP on a VR:
1. Enable multicast routing.
host1(config)#ip multicast-routing
2. (Optional) Create a VR or access a VR context.
host1(config)#virtual-router boston
NOTE: If you do not specify a VR, you can configure DVMRP on the default router.
You must enable and configure DVMRP on one or more interfaces for DVMRP to function.
See “Activating DVMRP on an Interface” on page 124. You can also set DVMRP limits for
the VR; see “Configuring DVMRP Limits” on page 125.
Activating DVMRP on an Interface
By default, DVMRP is not activated on an interface. Configuring any DVMRP parameter
on an interface automatically activates DVMRP on that interface. You can also activate
DVMRP on an interface and use the default parameters.
