Configuring Multicast Routing And Forwarding; Configuring Static Multicast Routes; Specifying The Longest Prefix Match Principle - HP FlexFabric 5950 series Configuration Manual

Configuring multicast routing and forwarding

Before you configure multicast routing and forwarding, complete the following tasks:
•
Configure a unicast routing protocol so that all devices in the domain can interoperate at the
network layer.
•
Enable PIM-DM or PIM-SM.

Configuring static multicast routes

To configure a static multicast route for a given multicast source, you can specify an RPF interface or
an RPF neighbor for the multicast traffic from that source.
To configure a static multicast route:
Step
1. Enter system view.
2. Configure a static
multicast route.
3. (Optional.) Delete static
multicast routes.

Specifying the longest prefix match principle

You can enable the device to use the longest prefix match principle for RPF route selection. For more
information about RPF route selection, see
To specify the longest prefix match principle for RPF route selection:
Step
1. Enter system view.
2. Enter MRIB view.
3. Specify the longest prefix
match principle for RPF route
selection.
