Overview
In IPv6 multicast implementations, the following types of tables implement multicast routing and
forwarding:
• Multicast routing table of an IPv6 multicast routing protocol—Each IPv6 multicast routing protocol
has its own multicast routing table, such as the IPv6 PIM routing table.
• General IPv6 multicast routing table—The multicast routing information of different IPv6 multicast
routing protocols forms a general IPv6 multicast routing table.
• IPv6 multicast forwarding table—The IPv6 multicast forwarding table guides the forwarding of IPv6
multicast packets.
An IPv6 multicast forwarding table consists of a set of (S, G) entries. Each entry contains 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 contains all 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 routing-capable firewalls and UTM devices.
IPv6 multicast routing and forwarding can be configured only at the CLI.
