Configuring DVMRP Routing Modes
You can configure DVMRP for either forwarding or unicast routing mode. In forwarding mode, DVMRP operates its protocol normally (for example, it does the routing as well as multicast data forwarding). In unicast routing mode, you can use DVMRP for unicast routing only; to forward multicast data, enable PIM on that interface. To configure the mode, include the mode statement.
To configure DVMRP for multicast forwarding, include the mode forwarding statement:
mode forwarding;
To configure DVMRP for unicast routing, include the mode unicast-routing statement:
mode unicast-routing;
You can include these statements at the following hierarchy levels:
- [edit protocols dvmrp interface interface-name]
- [edit logical-systems logical-system-name protocols dvmrp interface interface-name]
The default mode is forwarding.
