R0106-HP MSR Router Series IP Multicast Configuration Guide(V7)

248
As shown in Figure 74, a tunnel is established between the multicast routers Router A and Router B. Router
A encapsulates the IPv6 multicast data in unicast IPv6 packets, and forwards them to Router B across the
tunnel through unicast routers. Then, Router B strips off the unicast IPv6 header and continues to forward
the IPv6 multicast data down toward the receivers.

Enabling IPv6 multicast routing
Enable IPv6 multicast routing before you configure any Layer 3 IPv6 multicast functionality in the public
network or VPN instance.

By default, IPv6 multicast routing is
disabled.
Configuring IPv6 multicast routing and forwarding
Before you configure 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.
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."
