TX Matrix Routing Engine Description

 

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 RE0 and RE1. If two Routing 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 Control Boardto be installed in the adjacent slot. RE0 installs below CB0, and RE1 installs above CB1. A Routing Engine does not power on if no Control Board is present in the adjacent slot.

The ports for connecting the Routing Engine to external management devices are located on the corresponding TX-CIP. The ports on TX-CIP in slotCIP0 connect to the Routing Engine in slot RE0, and the ports on TX-CIP-1 connect to the Routing Engine in slot RE1.

The TX Matrix router supports the Routing Engines listed in Table 1
