Example: Configuring DVMRP to Announce Unicast Routes

In this example, DVMRP is used to announce unicast routes used solely for multicast reverse-path forwarding (RPF). Include the mode unicast-routing statement at the [edit protocols dvmrp interface] hierarchy level. Redistribute static routes by including the static statement at the [edit routing-options] hierarchy level to export the routes to all DVMRP neighbors.
