Usage Guidelines

Usage Scenario

To check BGP VPWS connection information after configuring BGP VPWS, run the display mpls l2vpn connection command.

Prerequisites

BGP VPWS has been configured.

Precautions

If a device has large numbers of VPWS connections, filter undesired information by specifying related parameters when running the

display mpls l2vpn connection command. Otherwise, excessive output information may cause the following problems:

The displayed information is repeatedly refreshed and the desired information cannot be obtained.
The system does not respond because of long-time information traversing and searching.

Example

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

unknown-num	Number of unknown connections of an MPLS L2VPN instance.
up-num	Number of Up connections of an MPLS L2VPN instance.
total-num	Total number of connections of an MPLS L2VPN instance.
interface	AC interface connecting to a CE.
remote vc state	Status of the remote VC: up: The VC is set up successfully. down: The VC fails to be set up.
remote ce-id	ID of the remote CE that establishes a connection with the local CE.
remote vc label	VC label assigned to the local end by the remote end through BGP.
local vc state	Status of the local VC: up: The VC is set up successfully. down: The VC fails to be set up.
local ce-id	ID of the local CE.
local ce name	Name of the local CE.
local vc label	VC label generated by the local end.
peer id	Destination IP address of a VC.
tunnel policy	Tunnel policy applied to the CE connection.
tunnel type	Type of the tunnel used to transmit service data from the CE over the public network.
tunnel id	ID of the tunnel used to transmit service data from the CE over the public network.
primary or not	Whether a VC is a primary or secondary VC: primary. secondary.
