display mvpn ipv6 ipmsi

Function

The display mvpn ipv6 ipmsi command displays multicast virtual private network (MVPN) inclusive-provider multicast service interface (I-PMSI) tunnel configurations.

Format

display mvpn ipv6 { all-instance | vpn-instance vpn-instance-name } ipmsi [ verbose [ grpAddr | srcAddr ] ^* ]

Parameters

Parameter	Description	Value
all-instance	Displays I-PMSI tunnel configurations of all instances.	-
vpn-instance vpn-instance-name	Displays I-PMSI tunnel configurations of a specified VPN instance. vpn-instance-name specifies the name of 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 detailed I-PMSI tunnel configurations.	-
grpAddr	Displays I-PMSI tunnel configurations of a specified multicast group address. group-address specifies a multicast group address.	The address is in the format of X:X:X:X:X:X:X:X.
srcAddr	Displays I-PMSI tunnel configurations of a specified multicast source address. source-address specifies a multicast source address.	The address is in the format of X:X:X:X:X:X:X:X.

Usage Guidelines

Usage Scenario

After an MVPNv6 is configured, run the display mvpn ipv6 ipmsi command to check IPv6 MVPN I-PMSI tunnel configurations of a specified VPN instance to that you can determine whether the IPv6 MVPN is working properly. Running the display mvpn ipv6 ipmsi command on the root node of a tunnel displays MVPN I-PMSI tunnel configurations of the root node and all leaf nodes. Running the display mvpn ipv6 ipmsi command on a leaf node of a P2MP tunnel displays MVPN I-PMSI tunnel configurations of the leaf node and the root node.

Precautions

If an I-PMSI tunnel is not established, no command output is displayed for the display mvpn ipv6 ipmsi command.

Example

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 ipmsi** command output
Item	Description
MVPN local I-PMSI information for VPN-Instance	VPN instance to which MVPN I-PMSI tunnel information belongs.
Tunnel type	Tunnel type: mLDP P2MP LSP: P2MP tunnel created using mLDP. RSVP-TE P2MP LSP: P2MP tunnel created using RSVP-TE. BIER IPv6: BIERv6 tunnel.
Tunnel state	Tunnel state: Up. Down. The tunnel state is displayed only the root node of the tunnel. Leaf nodes are unaware of the tunnel status, and -- is displayed instead.
Tunnel ID	ID of the P2MP tunnel.
Src-dt6 SID	Source address of BIERv6 packets, which is used to differentiate MVPN instances.
Prefix Len	Prefix length.
MSID Len	MSID length.
Sub-domain ID	BIER sub-domain ID.
BFR prefix	BFR prefix.
Bit string ID	BIER tunnel ID.
P2MP ID	P2MP ID of a P2MP tunnel.
Extended tunnel ID	Extended ID of the P2MP tunnel.
Total number of (S, G)	Total number of (S, G) entries that use an S-PMSI tunnel to forward multicast data.
Opaque value	Opaque value.

Root	IP address of the tunnel root node. If a PE is the root node of a tunnel, only the local address is displayed and identified by local.
Leaf	IP address of a tunnel leaf node. When a PE functions as a leaf node of a tunnel, only the local address is displayed and identified by local.
BFR-ID	BFR-ID.
