•MPLS TE Preferred Path: Preferred tunnel path functions let you map pseudowires to specific TE tunnels. Attachment circuits are cross-connected to specific MPLS TE tunnel interfaces instead of remote provider-edge router IP addresses (reachable using Interior Gateway Protocol [IGP] or Label Distribution Protocol [LDP]).

High Availability

The router is intended for use in Enterprise networks that require high-availability. It is designed to provide high MTBF (Mean Time Between Failures) and low MTTR (Mean Time To Resolve) rates. This minimizes outages or and maximizes availability. The router achieves this using the following:

•Component redundancy

–Duplex power supplies

–Cooling systems

•Fault detection

•Management features

•High availability features

–Non-stop forwarding (NSF)—Cisco IOS XR Software supports forwarding without traffic loss during a brief outage of the control plane through signaling and routing protocol implementations for graceful restart extensions as standardized by the IETF, NSF requires neighboring nodes to be NSF-aware.

–Process restartability (minimum disruption restart)

–Stateful switchovers

–In-service software upgrades

–MPLS TE FRR

–Bidirectional Forwarding Detection (BFD)

–Standard IEEE 802.3ad link aggregation bundles

System Configurations

The router runs Cisco IOS XR Software on the following standalone chassis types, available in AC or DC versions:

•a 6-slot chassis

•a 10-slot chassis

Cisco Systems has long been a leader in networking technology, providing cutting-edge solutions for service providers and enterprise organizations alike. Among their standout products is the Cisco ASR 9000 Series Aggregation Services Routers, notably the A9K24X10GETR and the A9KMOD80TR models. These routers are engineered to deliver unmatched performance, scalability, and versatility for networks that require high bandwidth and low latency.

The Cisco ASR 9000 Series is built for the needs of today's complex service provider and enterprise networks. A significant feature of the A9K24X10GETR is its 24-port 10-Gigabit Ethernet module. This functionality allows for high-density connectivity, making it ideal for aggregating numerous connections to different parts of a network while maintaining optimal performance. Whether used for Internet service providers delivering high-speed connectivity or for enterprises looking to connect multiple branches, the A9K24X10GETR provides robust and reliable data transmission.

Further enhancing the capabilities of the ASR 9000 is the A9KMOD80TR module, which supports an extensive range of services. This module is designed to run a variety of technologies, including Layer 2 and Layer 3 services, MPLS (Multiprotocol Label Switching), and IPv6. Its ability to integrate seamlessly into existing infrastructures while providing the advanced features customers demand makes it an invaluable asset for network engineering teams.

Another cutting-edge technology present in the ASR 9000 Series is its support for eBGP (External Border Gateway Protocol), which plays a critical role in managing traffic across multiple networks. The routers are equipped with advanced telemetry features, empowering operators with real-time insights into network performance and health. Additionally, they come with integrated security features that protect against DDoS threats and other vulnerabilities.

In summary, Cisco's ASR 9000 Series, particularly the A9K24X10GETR and A9KMOD80TR, combines high-density connections, extensive service support, and advanced security and telemetry capabilities. These routers are perfect for demanding environments where reliable performance and adaptability are crucial. With their focus on innovation and performance, Cisco continues to shape the future of networking technology.
