Hot Standby Router Protocol (HSRP)

Multicast load splitting across equal-cost paths


Protocol Independent Multicast (PIM) is a [Multicast](/multicast) [routing](/routing) protocol.  It has no inherent redundancy capabilities and its operation is completely independent of [FHRP Protocols](/fhrp-protocols) such as [HSRP](/hot-standby-router-protocol-hsrp).  As a result, IP multicast traffic **is forwarded not necessarily by the same device as is elected by HSRP**. The HSRP Aware PIM feature provides **consistent IP multicast forwarding** in a redundant network with virtual routing groups enabled.
