R21xx-HP FlexFabric 11900 IP Multicast Configuration Guide

• Configure an IPv6 unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
• Configure IPv6 PIM-DM or IPv6 PIM-SM.
Configuring the RPF route selection rule
You can configure the router to select the RPF route based on the longest prefix match principle. For more
information about RPF route selection, see "RPF check process."

Command Remarks
1. Enter system view.

2. Configure the device to select
the RPF route based on the
longest prefix match.
ipv6 multicast longest-match
By default, the route with the
highest priority is selected as the
RPF route.
Configuring IPv6 multicast load splitting
By configuring per-source or per-source-and-group load splitting, you can optimize the traffic delivery
when multiple IPv6 multicast data streams are handled.

2. Configure IPv6 multicast load
splitting.
ipv6 multicast load-splitting
{source | source-group }
By default, IPv6 multicast load
splitting is disabled.
Configuring an IPv6 multicast forwarding boundary
IPv6 multicast packets do not travel infinitely in a network. The IPv6 multicast data of each IPv6 multicast
group must be transmitted within a definite scope. A multicast forwarding boundary sets the boundary
condition for the IPv6 multicast groups in the specified range or scope. If the destination address of an
IPv6 multicast packet matches the set boundary condition, the packet is not forwarded. Once an IPv6
multicast boundary is configured on an interface, this interface can no longer forward IPv6 multicast
packets (including those sent from the local device) or receive IPv6 multicast packets.
