Overview
IPv6 PIM provides IPv6 multicast forwarding by leveraging IPv6 unicast static routes or IPv6 unicast
routing tables generated by any IPv6 unicast routing protocol, such as RIPng, OSPFv3, IS-ISv6, or BGP4+.
IPv6 PIM uses an IPv6 unicast routing table to perform RPF check to implement IPv6 multicast forwarding.
Independent of the IPv6 unicast routing protocols running on the device, IPv6 multicast routing can be
implemented as long as the corresponding IPv6 multicast routing entries are created through IPv6 unicast
routes. IPv6 PIM uses the RPF mechanism to implement IPv6 multicast forwarding. When an IPv6
multicast packet arrives on an interface of the device, RPF check is performed on it. If the RPF check
succeeds, the device creates the corresponding routing entry and forwards the packet. If the RPF check
fails, the device discards the packet. For more information about RPF, see Appendix Protocol References.
Based on the implementation mechanism, IPv6 PIM supports the following modes:
• Protocol Independent Multicast–Dense Mode for IPv6 (IPv6 PIM-DM)
• Protocol Independent Multicast–Sparse Mode for IPv6 (IPv6 PIM-SM)
• Protocol Independent Multicast Source-Specific Multicast for IPv6 (IPv6 PIM-SSM)
In this document, a network comprising IPv6 PIM routers is referred to as an "IPv6 PIM domain."
The term "router" in this document refers to both routers and routing-capable firewalls and UTM devices.
IPv6 PIM can be configured only at the CLI.
