Protocol Independent Multicast, Sparse Mode (PIM-SM)

Adds a Rendezvous Point router to avoid

multicast-data flooding. Use PIM–SM when

receivers for multicast data are sparsely

distributed throughout the network.

Protocol Independent Multicast, Split MultiLink Trunking

(PIM-SMLT)

Builds a virtual switch that represents the two

switches of the split multilink trunk core.

provider core router (P router)

A router in the core of a provider network that

supports tunnels between provider edge (PE)

routers, but is not connected to a customer

device. P routers do not need to support VPN

functionality.

provider edge (PE)

A router in the provider network that connects to

customer edge (CE) devices located at customer

sites. PE routers support VPN functionality.

Within a single VPN, pairs of PE routers connect

through a multiprotocol label switching (MPLS)

label switched path (LSP) tunnel. A PE router

can act as a P router.
