Routing device having multiple logical routers

摘要

Techniques are described for implementing one or more logical routers within a single physical routing device. These logical routers, as referred to herein, are logically isolated in the sense that they achieve operational and organizational isolation within the routing device without requiring the use of additional or redundant hardware, e.g., additional hardware-based routing controllers. The routing device may, for example, include a computing platform, and a plurality of software process executing within the computing platform, wherein the software processes operate as logical routers. The routing device may include a forwarding component shared by the logical routers to forward network packets received from a network in accordance with the forwarding tables.

1. A device comprising:
a computing platform; one or more programmable processors configured to execute a plurality of software processes within the computing platform, wherein the plurality of software processes operate as logical routers; a first logical router operating as a router within a first one of a pair of redundant networks; a second logical router operating as a router within a second one of the pair of redundant networks, wherein the first logical router and the second logical router operate as logically isolated routers within the routing device; and a software multiplexer to receive commands from a management process and to distribute the commands to at least one of the first logical router and the second logical router in accordance with configuration sessions from which the commands were received.
