Configuring IPv6 Multicast Routing and Forwarding
Configuration Prerequisites
Before configuring IPv6 multicast routing and forwarding, complete the following tasks:
z Configure an IPv6 unicast routing protocol so that all devices in the domain are
interoperable at the network layer.
z Configure IPv6 PIM-DM or IPv6 PIM-SM.
Before configuring IPv6 multicast routing and forwarding, prepare the following data:
z Maximum number of downstream nodes for a single entry in the IPv6 multicast forwarding
table
z 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 RPF Check process .
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.

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
