Changes in Behavior and Syntax
This section lists the changes in behavior of Junos Extension Toolkit features and changes in the syntax of Junos OS statements and commands from Junos OS Release 19.1R1.
Updates to RIB service APIs for flexible tunnel gateway—From Junos OS Releases 18.2X75-D21 or earlier, RIB service APIs support flexible tunnel gateways. The RIB service APIs are updated to ensure forward compatibility in releases after Junos OS Release 18.4R1. The Protobuf IDL field number for flexible_tunnel_profile in RouteGateway is changed from the original value. The new value is not compatible from Junos OS Release 18.2X75-D21 and earlier. When updating Junos OS from 18.2X75-D21 and earlier releases, you must rebuild the applications that use the RIB service APIs with the new IDLs.
