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:
one or more programmable processors configured to execute a plurality of software processes, wherein the plurality of software processes operate as logical routers, wherein the logical routers include a first logical router and a second logical router; a management process having a command line interface to receive commands from a plurality of clients by respective configuration sessions over a network, wherein the command line interface of the management process supports a text-based command syntax that allows each of the plurality of clients to specify a command to designate one of the logical routers for configuration using the respective configuration session; and a software multiplexer to receive the commands from the management process and to distribute the commands to at least one of the first logical router and the second logical router in accordance with the designation by the clients.
