9.4 Configuring the Multicast Routing Policy

Configuring a multicast routing policy involves configuring the longest match of the multicast
route, configuring multicast load splitting, and setting a multicast load splitting weight.

9.4.1 Establishing the Configuration Task

Before configuring multicast routing policies, familiarize yourself with the applicable
environment, pre-configuration tasks, and required data. This can help you complete the
configuration task quickly and accurately.
Applicable Environment
If multiple equal-cost unicast routes exist when a multicast switch select an upstream interface,
you can configure the switch to the RPF switch by using one of the following methods:

9.4.2 Configuring Longest Match of Multicast Route

If the longest match principle is configured for route selection, a multicast device prefers the
route with the longest matched mask. If the mask lengths of multiple routes are the same, the

Run the display multicast [ vpn-instance vpn-instance-name | all-instance ] rpf-info
source-address [ group-address ] [ rpt | spt ] command to check RPF routing information
of a specified multicast source.
By default, the switch chooses the route with the largest next-hop address.
According to the longest match rules, you can configure the switch to select the route with
the destination address that longest matches the address of the source of the packet.
You can configure load splitting among these switchs. Performing load splitting of
multicast traffic according to different policies can optimize network traffic when multiple
multicast data flows exist.
