display mvpn ipv6 spmsi

Function

The display mvpn ipv6 spmsi command displays selective-provider multicast service interface (S-PMSI) tunnel configurations of VPN instances.

Format

display mvpn ipv6 { 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.	-
srcAddr	Specifies a multicast source.	-

Usage Guidelines

Usage Scenario

To determine whether the S-PMSI tunnels of a VPN instance are working properly, run the display mvpn ipv6 spmsi command to check S-PMSI tunnel configurations.

Precautions

If no S-PMSI tunnels are established, no output is displayed for the display mvpn ipv6 spmsi command.

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

**Table 1** Description of the **display mvpn ipv6 spmsi** command output
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	S-PMSI A-D route type.
Total number of tunnel	Number of P2MP tunnels.
Total number of (S, G)	Total number of (S, G) entries that use an S-PMSI tunnel to forward multicast data.
Total matched number of (S, G)	Total number of (S, G) entries that use this PMSI tunnel to forward multicast data.
Tunnel type	Tunnel type: mLDP P2MP LSP. RSVP-TE P2MP LSP. BIER IPv6.
Tunnel state	Tunnel state: Up. Down. Up or Down is displayed only on the tunnel's root node. Leaf nodes are unaware of the tunnel state, and -- is displayed on them instead.
Tunnel ID	ID of a P2MP tunnel.
Src-dt6 SID	Source address of BIERv6 packets, which is used to differentiate MVPN instances.
Prefix Len	Prefix length.
MSID Len	Length of MSID.
Sub-domain ID	BIER sub-domain ID.
BFR prefix	IPv6 address of BFR-prefix.
Bit string ID	BitString ID.
P2MP ID	P2MP ID of a P2MP tunnel.
Extended tunnel ID	Extended ID of a P2MP tunnel.
Opaque value	Opaque value.
Root-ip	IP address of an mLDP P2MP tunnel's root node.
Root	IP address of a tunnel's root node. If the PE functions as the tunnel's root node, its IP address is displayed and is identified with local.
Leaf	IP address of a tunnel's leaf node. If the PE functions as the tunnel's leaf node, its IP address is displayed and is identified with local.
