When Bidirectional PIM (PIM-BiDir) is deployed at a site, the multicast route state created is S,G.
PIM-BiDir is a multicast routing protocol used in some enterprise and service provider networks. It is designed to simplify the management of multicast traffic by allowing for a single, bidirectional multicast tree to be created for each group. This is different from traditional multicast routing protocols like PIM-SM (Protocol Independent Multicast-Sparse Mode), which use separate trees for the source and receiver of each multicast group.
In PIM-BiDir, a multicast tree is created only when there is an active source sending traffic to the group. The tree is bidirectional, which means that traffic can flow in both directions between the source and receivers. The tree is rooted at the source, and all receivers join the tree by sending a join message towards the root.
The multicast route state created by PIM-BiDir is S,G, where S is the source IP address and G is the multicast group address. This route state is used to represent the active source and its associated multicast group. When there are no active sources sending traffic to the group, the S,G route is removed from the routing table.
To summarize, when Bidirectional PIM is deployed at a site, the multicast route state created is S,G, which represents the active source and its associated multicast group.
