Pinging Layer 2 VPNs

Enter the ping mpls l2vpn command with the following syntax. Table 204 describes the ping mpls l2vpn command options.

user@host> ping mpls l2vpn interface interface-name | instance l2vpn-instance-name local-site-id local-site-id-number remote-site-id remote-site-id-number <bottom-label-ttl> <exp forwarding-class> <count number> <source source-address> <detail>

To quit the ping mpls l2vpn command, press Ctrl-C.

Alternatively, you can use the J-Web interface. (See Checking MPLS Connections from the J-Web Interface.)
