Configuring BGP to Gather Interprovider and Carrier-of-Carriers VPNs Statistics

You can configure BGP to gather traffic statistics for interprovider and carrier-of-carriers VPNs.

To configure BGP to gather traffic statistics for interprovider and carrier-of-carriers VPNs, include the traffic-statistics statement:

traffic-statistics {

    file file-name <world-readable | no-world-readable>;

    interval seconds;

}

For a list of the hierarchy levels at which you can include the traffic-statistics statement, see the summary section for this statement.

NOTE: Traffic statistics for interprovider and carrier-of-carriers VPNs are available only for IPv4. IPv6 is not supported.

If you do not specify a filename, the statistics are not written to a file. However, if you have included the traffic-statistics statement in the BGP configuration, the statistics are still available and can be accessed by means of the show bgp group traffic-statistics group-name command.

To account for traffic from each customer separately, separate labels must be advertised for the same prefix to the peer routers in different groups. To enable separate traffic accounting, you need to include the per-group-label statement in the configuration for each BGP group. By including this statement, statistics are collected and displayed that account for traffic sent by the peers of the specified BGP group.

If you configure the statement at the [edit protocols bgp family inet] hierarchy level, rather than configuring it for a specific BGP group, then the traffic statistics are shared with all BGP groups configured with the traffic-statistics statement but not configured with the per-group-label statement.

To account for traffic from each customer separately, include the per-group-label statement in the configuration for each BGP group:

per-group-label;

For a list of the hierarchy levels at which you can include the per-group-label statement, see the summary section for this statement.

The following shows a sample of the output to the traffic statistics file:
