IPv6 multicast routing and forwarding are based on IPv6 multicast routing and forwarding tables. IPv6 multicast routing and forwarding control are implemented based on multicast routing management.
In IPv6 multicast implementation on the NetEngine 8000 F, IPv6 multicast routing and forwarding involves two aspects:
Each multicast routing protocol has a routing table, for example, a PIM routing table.
Routing entries of each protocol are directly delivered to a multicast forwarding table. The multicast forwarding table controls the forwarding of multicast data packets.
A multicast routing protocol uses the RPF mechanism to generate multicast routing entries, ensuring that multicast data packets are transmitted along correct paths. A system performs an RPF check based on the following types of routes:
IPv6 unicast routes
An IPv6 unicast routing table has the shortest path to each destination.
Static IPv6 multicast routes
A static IPv6 multicast routing table contains statically configured RPF routes.
IPv6 multicast route management is used to manage IPv6 multicast routing tables, control the generation of IPv6 multicast routes, and change IPv6 multicast RPF routes.
