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.
