Enabling IPv6 Multicast Routing
Before configuring any Layer 3 IPv6 multicast functionality, you must enable IPv6 multicast routing.
Follow these steps to enable IPv6 multicast routing:

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:
• Minimum hop limit value required for an IPv6 multicast packet to be forwarded
• 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 more
information about RPF route selection, see 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.
Follow these steps to configure an IPv6 multicast routing policy:

Optional
The route with the highest priority is
selected as the RPF route by default
