Virtual Chassis

  • Ephemeral configuration database support for synchronous commit synchronize operations on MX Series Virtual Chassis (MX240, MX480, MX960, MX2010, and MX2020)—Starting in Junos OS Release 21.1R1, you can configure the ephemeral database to execute commit synchronize operations using a synchronous commit model on MX Series Virtual Chassis. The synchronous commit model enables you to reliably use the ephemeral database on devices that have graceful Routing Engine switchover (GRES) or non-stop routing (NSR) enabled. To use the synchronous commit model for the ephemeral database, configure the commit-synchronize-model synchronous statement at the [edit system configuration-database ephemeral] hierarchy level.
