Configuring IPv6 multicast routing and
forwarding
NOTE:
•
The types of interfaces that appear in any figures other than the network diagrams for configuration
examples are for illustration only. Some of them might be unavailable on your firewall.
• The IPv6 multicast routing and forwarding configuration is available only at the CLI.
Overview
In IPv6 multicast implementations, multicast routing and forwarding are implemented by routing and
forwarding tables:
• Each IPv6 multicast routing protocol has its own multicast routing table, such as the IPv6 PIM routing
table.
• The multicast routing information of different IPv6 multicast routing protocols forms a general IPv6
multicast routing table.
• The IPv6 multicast forwarding table helps guide the forwarding of IPv6 multicast packets. This is the
table that guides IPv6 multicast forwarding.
An IPv6 multicast forwarding table consists of a set of (S, G) entries. Each entry indicates the routing
information for delivering multicast data from a multicast source to a multicast group. If a router supports
multiple IPv6 multicast protocols, its IPv6 multicast routing table will include routes that these protocols
have generated. The router chooses the optimal route from the IPv6 multicast routing table based on the
configured multicast routing and forwarding policy and installs the route entry into its IPv6 multicast
forwarding table.
The term "router" in this document refers to both routers and Layer 3 firewalls.
