searches its IPv6 unicast routing table and finds that the outgoing interface to the source (the RPF
interface) is VLAN-interface 20. This means that the (S, G) entry is correct but the packet traveled
along a wrong path. The RPF check fails and the router discards the packet.

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."
