Security

•Cisco IOS XR Software: This software provides comprehensive network security features, including ACLs; control-plane protection; routing authentications; authentication, authorization, and accounting (AAA); TACACS+; IP Security (IPSec); Secure Shell (SSH) Protocol; SNMPv3; and leading Routing Policy Language (RPL) support.

•Layer 2 ACLs: You can use this security feature to filter packets under an EVC based on MAC addresses.

•Layer 3 ACLs: This feature matches ACLs by IPv4 protocol packet attributes.

•Security: Many critical security features are supported:

–Standard IEEE 802.1ad Layer 2 Control Protocol (L2CP) and bridge-protocol-data-unit (BPDU) filtering

–MAC limiting per EFP or bridge domain

–Unicast, multicast, and broadcast storm control blocking on any interface or port

–Unknown Unicast Flood Blocking (UUFB)

–Dynamic Host Configuration Protocol (DHCP) Snooping

–Unicast Reverse Path Forwarding (URPF)

–Control-plane security

•Secure Shell (SSH)

•Authorization, Admission, Accounting (AAA)

•Control Plane Policing (CoPP)

Initial Router Configuration

The initial configuration of the Cisco ASR 9000 Series Aggregation Services Router is determined automatically by the software when you boot the router; you need not set up any general configuration information. Also there is no explicit configuration needed to make a particular RSP active. It becomes the active RSP when chosen automatically by the software upon boot.

Since there are not multiple RSP pairs in this router, the only RSP choices are RSP0 and RSP1. Typically, the lower numbered slot is the chosen RSP. If that RSP is not available the software chooses the RSP in the other slot as the route process controller, making it the primary RSP. During fail over or switch over, the active role migrates to the standby RSP.

Management Interfaces

Although there is no need to set up general router configuration information, you do need to configure management interfaces manually. Configure management ports on RSP0, RSP1, or both at the same time:

•Telnet

•Secure Shell (SSH)

•Console Server

The router provides different router management interfaces, described in the following sections:

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.
