The Cisco XR 12000 Series router is a fully modular, highly scalable router that provides a secure, scalable IP next-generation network platform for service providers. It supports multiple applications and services, including voice, data, video, and content delivery, and helps service providers improve service quality and reduce operating costs.
The Cisco XR 12000 series router combines Cisco IOS XR software with the proven Cisco 12000 hardware platform to deliver secure virtualization, continuous operation and multi‑service expansion for telecom operators. The document explains how the Service Separation Architecture (SSA) isolates each logical routing instance, ensuring that a failure in one service (e.g., public Internet) does not affect another (e.g., private VPN).
Key hardware features include redundant power supplies, fans, controllers and processing components, hot‑swap (OIR) support, ECC memory for error correction, and a modular distributed architecture that enables online software upgrades (ISSU) without service interruption. The manual also points to Cisco support resources and contact information for further assistance. This manual is written in Chinese.
