Tracing MBGP MVPN Traffic and Operations

 

To trace MBGP MVPN traffic, you can specify options with the traceoptions statement:

  1. Specify the name of one or move MVPN trace files using the file option for the traceoptions at the [edit routing-instances routing-instance-name protocols mvpn] hierarchy level or at the [edit protocols mvpn] hierarchy level:

    The file option includes the following sub-options:

    • filename—Specify the name of the file to receive the output of the tracing operation. Enclose the name within quotation marks. All files are placed in the directory /var/log.

    • files number—(Optional) Maximum number of trace files. When a trace file named trace-file reaches its maximum size, it is renamed trace-file.0, then trace-file.1, and so on, until the specified maximum number of trace files specified is reached. Then the oldest trace file is overwritten.

    • size size—(Optional) Maximum size of each trace file. When a trace file named trace-file reaches its maximum size, it is renamed trace-file.0, then trace-file.1, and so on, until the maximum number of trace files is reached. Then the oldest trace file is overwritten.

    • world-readable | no-world-readable—(Optional) Enable unrestricted file access or restrict file access to the user who created the file.

  2. Specify the flag option for the traceoptions statement:
