Abstract
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.
