TPA

Third Party Application (TPA) manages the communication between IOS-XR and Linux applications running on the router. TPA controls how Linux applications access the network through IOS-XR, including update source configuration for routing Linux traffic through specific interfaces, east-west interface forwarding between VRFs, and statistics collection for monitoring TPA activity.
