display mvpn spmsi

Function

The display mvpn spmsi command displays selective-provider multicast service interface (S-PMSI) tunnel configurations of VPN instances.

Format

display mvpn { all-instance | vpn-instance vpn-instance-name } spmsi [ verbose [ grpAddr | srcAddr ] ^* ]

Parameters

Parameter	Description	Value
all-instance	Displays S-PMSI tunnel configurations of all VPN instances.	-
vpn-instance vpn-instance-name	Displays S-PMSI tunnel configurations of a specified a VPN instance.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string.
verbose	Displays the detailed S-PMSI tunnel configurations of VPN instances.	-
grpAddr	Specifies a multicast group.	The value ranges from 224.0.1.0 to 239.255.255.255, in dotted decimal notation.
srcAddr	Specifies a multicast source.	The value is in dotted decimal notation.

Usage Guidelines

Usage Scenario

To determine whether the S-PMSI tunnels of a VPN instance are working properly, run the display mvpn spmsi command to check S-PMSI tunnel configurations.

Precautions

If no S-PMSI tunnels are established, no output is displayed for the display mvpn spmsi command.

The actual command output varies according to the device. The command output here is only an example.

Item	Description
MVPN local S-PMSI information for VPN-Instance	VPN instance to which S-PMSI tunnel information belongs.
S-PMSI A-D Route Type	Type of S-PMSI AD route. (S,G): Route from a specified multicast source to a specified multicast group. (,G): Route from any multicast sources to a specified multicast group. (,*): Route from any multicast sources to any multicast group.
Total number of tunnel	Number of tunnels. Leaf nodes cannot identify S-PSMI tunnel types.
Total number of (S, G)	Total number of (S, G) entries that use an S-PMSI tunnel to forward multicast data.
Tunnel type	P2MP tunnel type: mLDP P2MP LSP. RSVP-TE P2MP LSP. BIER tunnel type: BIER. BIER IPv6: BIERv6.
Tunnel state	Tunnel state: Up: The tunnel operates normally. Down: The tunnel is down. This parameter is displayed as. - only if the root node's state of a tunnel is displayed as Up or Down and the leaf node is unaware of the tunnel state.
Tunnel ID	ID of a P2MP tunnel.

BFR-ID	BIER BFIR ID.
Root	IP address of a root node. If this command is run on the root node, the root node IP address and local are displayed.
Leaf	IP address of a leaf node. If this command is run on a leaf node, the leaf node IP address and local are displayed.
