New and Changed Features


This section describes the new features and enhancements to existing features in Juniper Extension Toolkit 19.1R1.


Updates to RIB service APIs and new flexible tunnel APIs—Starting in Junos OS Release 19.1R1, we support flexible Virtual Extensible LAN (VXLAN) tunnels, which are comprised of the following components:

  • Static IPv4 or IPv6 routes

  • Tunnel encapsulation profiles

  • Tunnel de-encapsulation profiles

The controllers in a data center environment enable you to program these components into Juniper Networks devices that support flexible VXLAN tunnels.

Updates in the RIB service APIs—new flexible_tunnel_profile field in the object RouteGateway, and RPC RouteRRemoveMatching() and new related request/reply objects (RouteRemoveMatchingRequest and RouteOperReply))—enable you to associate an IPv4 or IPv6 static route with a tunnel encapsulation profile.

With the new flexible tunnel profile APIs, you can fully define tunnel encapsulation and de-encapsulation profiles. The flexible tunnel service APIs enable you to perform the bulk addition, modification, and deletion of de-encapsulation profiles and view a specific de-encapsulation profile.

System Management

  • Tracing support for individual JET application files—Previously you could configure traceoptions for all applications. Now you can do also configure traceoptions for an individual application file. If you configure traceoptions both globally (all applications) and locally (by application file), the local configuration has the higher priority.
