spmsi-tunnel (VPN instance IPv6 address family MVPN view)

Function

The spmsi-tunnel command creates and then displays the MVPN selective-provider multicast service interface (S-PMSI) view.

The undo spmsi-tunnel command deletes all MVPN S-PMSI configurations.

By default, the MVPN S-PMSI view does not exist.

Usage Guidelines

Usage Scenario

PMSI tunnels are the logical tunnels used by the public network to transmit VPN multicast data, and P-tunnels are the actual tunnels used by the public network to transmit VPN multicast data. PMSI tunnels are classified as I-PMSI or S-PMSI tunnels.

I-PMSI:An I-PMSI tunnel connects to all the PEs on an MVPN.The multicast data sent over an I-PMSI tunnel can be received by all PEs on the MVPN. In a VPN instance, one PE corresponds only to one I-PMSI tunnel.
S-PMSI:An S-PMSI tunnel connects to the sender and receiver PEs of specific multicast sources and groups. The multicast data sent over an S-PMSI tunnel is received only by PEs interested in the data. In a VPN instance, one PE can correspond to multiple S-PMSI tunnels.
S-PMSI tunnels can be established using P2MP TE or mLDP. Before configuring switching between I-PMSI and S-PMSI tunnels, run the spmsi-tunnel command to display the MVPN S-PMSI view.

Prerequisites

The MVPN I-PMSI view has been displayed using the ipmsi-tunnel command (if you want to run the spmsi-tunnel command), or the undo ipmsi-tunnel command has been run (if you want to run the undo spmsi-tunnel command).

Follow-up Procedure

Run the group (IPv6 MVPN S-PMSI view) command to configure the address pool range and criteria for switching between I-PMSI and S-PMSI tunnels.

Precautions

Running the undo spmsi-tunnel command deletes all configurations in the IPv6 MVPN S-PMSI view. Exercise caution when running the command.
