Protocol-Independent Multicast (PIM) is a family of multicast routing protocols for Internet Protocol (IP) networks that provide one-to-many and many-to-many distribution of data over a LAN, WAN or the Internet. It is termed protocol-independent because PIM does not include its own topology discovery mechanism, but instead uses routing information supplied by other routing protocols. PIM is not dependent on a specific unicast routing protocol; it can make use of any unicast routing protocol in use on the network. PIM does not build its own routing tables. PIM uses the unicast routing table for reverse path forwarding.
Interoperability between multicast protocol variants
A network device in a network is provided. During operation, the network device can operate as a first rendezvous point (RP) of a Bidirectional Protocol Independent Multicast (PIM-BIDIR) instance and also as a first RP of a PIM sparse mode (PIM-SM) instance. Here, the PIM-BIDIR instance can be deployed in a first segment of the network and the PIM-SM instance can be deployed in a second segment of the network. The network device can receive information associated with a first source of a first multicast group from a second RP of the PIM-SM instance. Subsequent to receiving a first join request for the first multicast group via the PIM-BIDIR instance, the network device can send a second join request of the PIM-SM instance to the first source based on the received information and forward multicast traffic received from the first source via a multicast tree of the PIM-BIDIR instance.

Broadcast, Unknown Unicast, and Link-Local Multicast Traffic Support Using Locator / Identifier Separation Protocol and Protocol Independent Multicast-Source-Specific Multicast
PendingUS20260156012A1Special service provision for substationNetworks interconnectionInternet trafficProtocol Independent Multicast
Systems, devices, and methods support network traffic, for example, Broadcast, unknown Unicast, and link-local Multicast (BUM) traffic, in an overlay by utilizing Protocol Independent Multicast (PIM)-Source-Specific Multicast (SSM) in an underlay, while removing dependency on PIM-Any Source Multicast (ASM). A mapping system receives a mapping registration message and / or a mapping request message of a candidate device configured with a virtual network instance, for example, a Layer 2 Virtual Network Instance (L2VNI) implemented with layer 2 flooding. In response to receiving the mapping registration message, the mapping system transmits a mapping notification message to one or more member devices of an underlay group associated with the L2VNI. The mapping notification message indicates that the candidate device has joined the underlay group. In response to receiving the mapping request message, the mapping system transmits, to the candidate device, a list indicating that the member device(s) intends to transmit the network traffic.
