PIM Source-Specific Multicast—The PIM source-specific multicast (SSM) routing protocol
supports SSM implementation and is derived from PIM-SM.
PIM Sparse Mode (PIM-SM)—IPv6 multicast provides support for intra domain multicast routing
using PIM sparse mode (PIM-SM).
PIM Embedded RP Support—Embedded RP support allows the device to learn RP information using
the multicast group destination address instead of the statically configured RP.
PIM Accept Register—supports the PIM accept register feature to perform PIM-SM register
message filtering at the RP.
