    Using the J-Web Ping MPLS Tool

    Before using the ping MPLS feature, make sure that the receiving interface on the VPN or LSP remote endpoint has MPLS enabled, and that the loopback interface on the outbound node is configured as 127.0.0.1. The source address for MPLS probes must be a valid address on the device.

    To use the ping MPLS tool:

    1. Select Troubleshoot>Ping MPLS from the task bar.
    2. Next to the ping MPLS option you want to use, click the expand icon.
    3. Enter information into the Ping MPLS page (see Table 1).
