trace-prefix route-distinguisher (BMP Session IPv4 VPN view)

Function

The trace-prefix route-distinguisher command configures BMP to monitor the trace data of a VPNv4 route with a specified RD and route prefix as well as the IPv4 VPN unicast route transformed from the VPNv4 route.

The undo trace-prefix route-distinguisher command restores the default configuration.

By default, BMP does not monitor the trace data of a specified VPNv4 route or IPv4 VPN unicast route transformed from the VPNv4 route.

Usage Guidelines

Usage Scenario

By default, BMP does not report the trace data of BGP routes on a device. As a result, you can only manually query the trace data of the device's BGP routes.

To resolve this issue, run the trace-prefix route-distinguisher command on the device after a connection is established between the device and BMP server. The command configures BMP to monitor the trace data of a specified VPNv4 route and the IPv4 VPN unicast route transformed from the VPNv4 route in real time. After the configuration, BMP can monitor how the routes are processed in response to the following main items:

Import route-policy for routes received from a specified peer (configured using the peer route-policy import command)
Export route-policy for routes to be advertised to a specified peer (configured using the peer route-policy export command)
Export route-policy for BGP VPN routes (configured using the export route-policy command)
Import route-policy for BGP VPN routes (configured using the import route-policy command)
Route-policy for routes imported using the network command
Route-policy for summary routes
Route withdrawal

Example

# Configure BMP to report the trace data of a specified VPNv4 route and the IPv4 VPN unicast route (transformed from the VPNv4 route) to a BMP server.
