the candidate configuration file being committed. If no errors are found, the configuration

Routing Engine automatically synchronizes its configuration with the master

On the TX Matrix router, synchronization only occurs between the Routing Engines within
the same chassis. 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.
On the TX Matrix Plus router, synchronization only occurs between the Routing Engines
within the switch-fabric chassis and when synchronization is complete, the new
configuration is then distributed to the Routing Engines on the line-card chassis (LCC).
That is, the master Routing Engine on the TX Matrix Plus router distributes the
configuration to the master Routing Engine on each LCC. Likewise, the backup Routing
Engine on the TX Matrix Plus router distributes the configuration to the backup Routing
Engine on each LCC.
