Bypass LSP statistics for Junos Telemetry Interface

You can export statistics for bypass label-switched paths (LSPs). Previously, only statistics for the primary LSP path were exported. The ability to export bypass LSP statistics helps to monitor the efficiency of global convergence when the bypass LSP is used to carry traffic during a link or node failure. 

Statistics are exported for the following: 

•  Bypass LSP originating at the ingress router of the protected LSP 
•  Bypass LSP originating at the transit router of the protected LSP 
•  Bypass LSP protecting the transit LSP as well as the locally originated LSP 

When the bypass LSP is active, traffic is exported both on the bypass LSP and the ingress (protected) LSP. To provision the sensor to export data through gRPC, use the telemetrySubcribe RPC to specify telemetry parameters. For streaming through UDP, all parameters are configured at the [edit services analytics] hierarchy level. Streaming telemetry data through gRPC also requires you to download the OpenConfig for Junos OS module. You must also include the sensor-based-stats statement at the [edit protocols mpls] hierarchy level.
