display mvpn ipmsi

Function

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

Format

display mvpn { 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 value ranges from 224.0.1.0 to 239.255.255.255, in dotted decimal notation.
srcAddr	Displays I-PMSI tunnel configurations of a specified multicast source address. source-address specifies a multicast source address.	The value is in dotted decimal notation.

Usage Guidelines

Usage Scenario

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

Example

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