Any-source multicast

Any-source multicast (ASM) is the older and more usual form of multicast where multiple senders can be on the same group/channel, as opposed to source-specific multicast where a single particular source is specified. Commonly, any-source multicast is used in IGMP version 2; however, it can also be used in PIM-SM, MSDP, and MBGP. ASM utilizes IPv4 in association with the previously stated protocols; in addition, MLDv1 protocol is used for IPv6 addresses.
