Configuring IPv6 Multicast Routing and Forwarding

Configuration Prerequisites
Before configuring IPv6 multicast routing and forwarding, complete the following tasks:
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.
Before configuring IPv6 multicast routing and forwarding, prepare the following data:
Maximum number of downstream nodes for a single entry in the IPv6 multicast forwarding table
Maximum number of entries in the IPv6 multicast forwarding table

Configuring an IPv6 Multicast Routing Policy

You can configure the router to determine the RPF route based on the longest match principle. For
details about RPF route selection, refer to
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.
Follow these steps to configure an IPv6 multicast routing policy:
To do...
Enter system view
Configure the device to select
the RPF route based on the
longest match
Configure IPv6 multicast load
splitting

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. Presently, 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 on all interfaces that
support IPv6 multicast forwarding. A multicast forwarding boundary sets the boundary condition for the
IPv6 multicast groups in the specified range. If the destination address of an IPv6 multicast packet
matches the set boundary condition, the packet will not be 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.
