An AR Device Cannot Ping the Remote End After a VPN Instance Is Created on the AR

An AR Device Cannot Ping the Remote End After a VPN Instance Is Created on the AR

Possible Causes

  • The name of the VPN instance bound to the interface connected to the remote end is not specified in the ping command.

  • The route of the VPN instance bound to the interface connected to the remote end is unreachable.

Troubleshooting Procedure

  1. Run the ping -vpn-instance vpn-instance-name command to ping the remote end by specifying the VPN instance name.
    NOTE:
    If a VPN instance is bound to multiple interfaces of a device, run the ping -vpn-instance command to ping the remote end. When running this command, specify the source IP address. That is, specify the -a source-ip-address parameter in the ping -vpn-instance vpn-instance-name -a source-ip-address dest-ip-address command. Otherwise, the ping may fail.
  2. If the ping -vpn-instance vpn-instance-name command output shows that the route of the VPN instance is unreachable, run the ip route-static vpn-instance command to configure a static route for the VPN instance.
