Figure 75 RPF check process
When an IPv6 multicast packet arrives on POS 5/0/0/1 of Router C, because the interface is the
•
incoming interface of the (S, G) entry, the router forwards the packet to all outgoing interfaces.
When an IPv6 multicast packet arrives on POS 5/0/0 of Router C, because 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 POS 5/0/0/1. This means that the (S, G) entry is correct and the packet arrived along
a wrong path. The RPF check fails and the packet is discarded.

Enabling IPv6 multicast routing

Before configuring any Layer 3 IPv6 multicast functionality, enable IPv6 multicast routing.
To do...
1. Enter system view.
2. Enable IPv6 multicast routing.

Configuring IPv6 multicast routing and forwarding

Prerequisites

Before configuring IPv6 multicast routing and forwarding, complete the following tasks:
• Enable IPv6 forwarding and 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
•
Determine the minimum hop limit value required for an IPv6 multicast packet to be forwarded
•
Determine the maximum number of downstream nodes for a single entry in the IPv6 multicast
•
forwarding table
Determine the maximum number of entries in the IPv6 multicast forwarding table
•
Use the Command...
