Cisco 12000

From Wikipedia, the free encyclopedia

The Cisco 12000 is a series of large network routers designed and manufactured by Cisco Systems and marketed primarily to large service providers. It is also used in some enterprise networks. They are made with a variety of chassis sizes and types, all of which share compatible card interfaces. A 12000-series router is also called a Gigabit Switch Router or GSR.

Routers in this series are designed to provide IP and MPLS services. To maximize availability for service providers, these routers have robust features including redundant power supplies, standby route processors, resilient fabric, and alarm modules.

GSR line cards are available for Asynchronous Transfer Mode, Frame Relay, Packet over Sonet (POS), and Gigabit Ethernet protocols.
