The Routing Engine in the TX Matrix router maintains the routing tables used by the
routing matrix and controls the routing protocols that run on the routing matrix. The
TX Matrix router provides all routing tables, along with updates, to each T640 router in
the routing matrix.
You can install one or two Routing Engines in the TX Matrix router. The Routing Engines
install into the upper rear of the chassis in the slots labeled
Engines are installed, one functions as the master and the other acts as the backup. If
the master Routing Engine fails or is removed, and the backup is configured appropriately,
the backup restarts and becomes the master.
NOTE: We recommend that you run the same Junos OS release on the master
and backup Routing Engines. If you elect to run different Junos OS releases
on the Routing Engines, a change in Routing Engine mastership can cause
one or all T640 routers to be logically disconnected from the TX Matrix router.
Each Routing Engine requires a TX-CB to be installed in the adjacent slot.
