What's Changed

General Routing

Before this change most list were ordered by the sequence in which the user configured the list items, for example a series of static routes. After this change the list order is determined by the system with items displayed in numerical sequence rather than by the order in which the items were configured. There is no functional impact to this change.
NOTE: In the CLI using the command request chassis feb slot slot-number offline if you make the primary FEB offline, a traffic loss warning message is displayed and the FEB offline request is rejected. If offline/restart is still intended for primary FEB, use force option in addition to the command. WARNING message displayed in the CLI: "warning: RCB and FEB work in the paired slot mode. FEB %s offline/restart will result in traffic loss and does not cause a switchover. Please re-try after initiating a mastership switchover using 'request chassis routing-engine master switch' CLI. If offline/restart is still intended, use 'force' option in addition to this CLI."

Ability to commit extension-service file configuration when application file is unavailable—When you set the optional option at the edit system extension extension-service application file file-name hierarchy level, the operating system can commit the configuration even if the file is not available at the /var/db/scripts/jet file path.

NETCONF <copy-config> operations support a file:// URI for copy to file operations (ACX Series, EX Series, MX Series, QFX Series, SRX Series, vMX, and vSRX)—The NETCONF <copy-config> operation supports using a file:// URI when <url> is the target and specifies the absolute path of a local file.

ephemeral-db-support statement required to configure MSTP, RSTP, and VSTP in the ephemeral configuration database (ACX Series, EX Series, and QFX Series)—To configure Multiple Spanning Tree Protocol (MSTP), Rapid Spanning Tree Protocol (RSTP), or VLAN Spanning Tree Protocol (VSTP) in the ephemeral configuration database, you must first configure the ephemeral-db-support statement at the [edit protocols layer2-control] hierarchy level in the static configuration database.
