Configuring DVMRP
Distance Vector Multicast Routing Protocol (DVMRP) is the first of the multicast routing protocols and has a number of limitations that make this method unattractive for large-scale Internet use. DVMRP is a dense-mode-only protocol, and uses the flood-and-prune or implicit join method to deliver traffic everywhere and then determine where the uninterested receivers are. DVMRP uses source-based distribution trees in the form (S,G).
To configure the Distance Vector Multicast Routing Protocol (DVMRP), include the dvmrp statement:
dvmrp {disable;export [ policy-names ];import [ policy-names ];interface interface-name {disable;hold-time seconds;metric metric;mode (forwarding | unicast-routing);}rib-group group-name;traceoptions {file filename <files number> <size size> <world-readable | no-world-readable>;flag flag <flag-modifier> <disable>;}}
You can include this statement at the following hierarchy levels:
- [edit protocols]
- [edit logical-systems logical-system-name protocols]
By default, DVMRP is disabled.
