Chapter 1 Introducing to the Cisco ASR 9000 Series Aggregation Services Router

Router Overview

F I N A L D R A F T — C i s c o C o n f i d e n t i a l

•MST Access Gateway: This feature provides a resilient, fast-convergence mechanism for aggregating and connecting to Ethernet-based access rings.

L2VPN

The router uses L2VPNs, this offers the following:

•Virtual Private LAN Services (VPLS): VPLS is a class of VPN that supports the connection of multiple sites in a single, bridged domain over a managed IP/MPLS network. It presents an Ethernet interface to customers, simplifying the LAN and WAN boundary for service providers and customers, and enabling rapid and flexible service provisioning because the service bandwidth is not tied to the physical interface. All services in a VPLS appear to be on the same LAN, regardless of location.

•Hierarchical VPLS (H-VPLS): H-VPLS provides a level of hierarchy at the edge of the VPLS network for increased scale. QinQ access and H-VPLS pseudowire access options are supported.

•Virtual Private WAN Services/Ethernet over MPLS (VPWS/EoMPLS): EoMPLS transports Ethernet frames across an MPLS core using pseudowires. Individual EFPs or an entire port can be transported over the MPLS backbone using pseudowires to an egress interface or subinterface.

•Pseudowire redundancy: Pseudowire redundancy supports the definition of a backup pseudowire to protect a primary pseudowire that fails.

•Multisegment pseudowire stitching: Multisegment pseudowire stitching is a method for interworking two pseudowires together to form a cross-connect relationship.

Multicast

The router supports multicast, this offers the following:

•IPv4 Multicast: IPv4 Multicast supports Internet Group Management Protocol Versions 2 and 3 (IGMPv2/v3), Protocol Independent Multicast Source Specific Multicast (SSM) and Sparse Mode (SM), Multicast Source Discovery Protocol (MSDP), and Anycast Rendezvous Point (RP).

•IGMP v2/v3 Snooping: This Layer 2 mechanism efficiently tracks multicast membership on an L2VPN network. Individual IGMP joins are snooped at the VLAN level or pseudowire level and then summarizes results into a single upstream join message. In residential broadband deployments, this feature enables the network to send only channels that are being watched to the downstream users.

OAM

The router supports different types of operations, administration, and maintenance (OAM), this offers the following:

•E-OAM (IEEE 802.3ah): Ethernet link layer OAM is a vital component of EOAM that provides physical-link OAM to monitor link health and assist in fault isolation. Along with IEEE 802.1ag, Ethernet link layer OAM can be used to assist in rapid link-failure detection and signaling to remote end nodes of a local failure.

•E-OAM (IEEE 802.1ag): Ethernet Connectivity Fault Management is a subset of EOAM that provides numerous mechanisms and procedures that allow discovery and verification of the path through IEEE 802.1 bridges and LANs.

•MPLS OAM: This protocol supports label-switched-path (LSP) ping, LSP TraceRoute, and virtual circuit connectivity verification (VCCV).

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.
