Routing Engine Slots
You can install one or two Routing Engines in the PTX5000. The Routing Engines install into the Control
Boards labeled CB0 and CB1. If two Routing Engines are installed, one functions as the primary and the
other acts as the backup. If the primary Routing Engine fails or is removed and the backup is configured
appropriately, the backup restarts and becomes the primary.
Routing Engine Functions
The Routing Engine handles all routing protocol processes, as well as the software processes that control
the PTX5000 router's interfaces, the chassis components, system management, and user access to the
PTX5000. The routing and software processes run on top of a kernel that interacts with the Packet
Forwarding Engine.
The Routing Engine constructs and maintains one or more routing tables. From the routing tables, the
Routing Engine derives a table of active routes, called the forwarding table, which is then copied into the
Packet Forwarding Engine. The design of the ASICs allows the forwarding table in the Packet Forwarding
Engine to be updated without interrupting forwarding performance.
The Routing Engine includes the following functions and features:
