When an IPv6 multicast packet arrives on Vlan-interface 10 of Router C, as the interface is not the

incoming interface of the (S, G) entry, the router performs an RPF check on the packet: The router

searches its IPv6 unicast routing table and finds that the outgoing interface to Source (the RPF

interface) is Vlan-interface 20. This means the (S, G) entry is correct and packet arrived along a

wrong path. The RPF check fails and the packet is discarded.

Configuration Task List

Complete these tasks to configure IPv6 multicast routing and forwarding:

Configuring IPv6 Multicast

Routing and Forwarding

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:

Enter system view

Enable IPv6 multicast routing

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

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.
