ping vpn-config
Function
The ping vpn-config command checks whether configurations on both ends of a VPN are consistent, which can help you locate faults on the VPN connection.
Format
ping vpn-config peer-address peer-address vsi-name vsi-name [ pw-id pw-id ] [ local ] [ remote ]
Parameters
| Parameter | Description | Value |
|---|---|---|
| peer-address peer-address | Specifies the IP address of the peer PE. | - |
| vsi-name vsi-name | Specifies the name of the VSI on which the operation is performed. | The value is an existing VSI. |
| pw-id pw-id | Specifies the ID of the PW. | The value is an integer that ranges from 1 to 4294967295. This parameter cannot be specified in the BGP AD VPLS networking. |
| local | Indicates that the Request packet is encapsulated in LSP mode. | - |
| remote | Indicates that the Reply packet is encapsulated in LSP mode. | - |
Usage Guidelines
Usage Scenario
Using the ping vpn-config command, you can check whether configurations on both ends of a VPN are consistent, which can help you locate faults on the VPN connection.
The ping vpn-config command is used to send a Request packet from the local PE to the peer PE to obtain VPN configurations of the peer PE, such as the VSI name, status, PW type, MTU value, and number of CEs. After the local PE receives the VPN configuration of the peer PE, it displays the information on the local. This can help you locate the fault on the VPN.
Precautions
The ping vpn-config command is applied to VPLS networks, dynamic PWE3 networks, and VLL accessing the VPLS networks.
The timeout period of the ping vpn-config command is 10 seconds.
