Configuring IPv6 multicast routing and forwarding
This section describes how to configure IPv6 multicast routing and forwarding.
Configuration prerequisites
Before you configure IPv6 multicast routing and forwarding, complete the following tasks:
• Enable IPv6 forwarding and 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.
• Determine the minimum hop limit value required for an IPv6 multicast packet to be forwarded.
• Determine the maximum number of downstream nodes for a single entry in the IPv6 multicast
forwarding table.
• Determine the maximum number of entries in the IPv6 multicast forwarding table.
Configuring an IPv6 multicast routing policy
You can configure the router to select the RPF route based on the longest match principle. For more
information about RPF route selection, see Appendix Protocol References.
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 the device to select
the RPF route based on the
longest match.
multicast ipv6 longest-match
Optional.
The route with the highest priority is
selected as the RPF route by default.
3. Configure IPv6 multicast load
splitting.
multicast ipv6 load-splitting
{source | source-group }
Optional.
Disabled by default.
Configuring an IPv6 multicast forwarding range
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. You can define an IPv6 multicast forwarding range by
specifying boundary interfaces, which form a closed IPv6 multicast forwarding area.
You can configure the forwarding boundary for a specific IPv6 multicast group or an IPv6 multicast group
with the scope field in its group address being specified on all interfaces that support IPv6 multicast
