Release Information

Statement introduced in Junos OS Release 7.4.

Description

Configure the commit command to automatically result in a commit synchronize action between dual Routing Engines within the same chassis. The Routing Engine on which you execute the commit command (requesting Routing Engine) copies and loads its candidate configuration to the other (responding) Routing Engine. Each Routing Engine then performs a syntax check on the candidate configuration file being committed. If no errors are found, the configuration is activated and becomes the current operational configuration on both Routing Engines.

Synchronization only occurs between the Routing Engines within the same chassis. On the TX Matrix router, when synchronization is complete, the new configuration is then distributed to the Routing Engines on the T640 routers. That is, the master Routing Engine on the TX Matrix router distributes the configuration to the master Routing Engine on each T640 router. Likewise, the backup Routing Engine on the TX Matrix router distributes the configuration to the backup Routing Engine on each T640 router.

Note: When you configure nonstop active routing (NSR), you must include the commit synchronize statement. Otherwise, the commit operation fails.
