Chapter 4 Configuring Additional Router Features

Configuring Software Entitlement

Configuring Software Entitlement

Certain software and hardware features are enabled using software entitlement, which is a system that consists of a license manager on a Cisco IOS XR device that manages licenses for various software and hardware features. The license manager parses and authenticates a license before accepting it. The software features on the router use the license manager APIs to check out and release licenses. Licenses are stored in persistent storage on the router.

All core routing features are available for use without any license. In Cisco IOS XR Software

Release 3.7, the following features must be enabled with licenses:

•Layer 3 VPN

•Modular services card bandwidth

Refer to the Cisco ASR 9000 Series Aggregation Services Router System Management Configuration Guide for more information on configuring software licenses.

Configuration Limiting

The Cisco IOS XR software places preset limits on the configurations you can apply to the running configuration of a router. These limits ensure that the router has sufficient system resources (such as RAM) for normal operations. Under most conditions, these preset limits are sufficient.

In some cases, for which a large number of configurations is required for a particular feature, it may be necessary to override the preset configuration limits. This override can be done only if configurations for another feature are low or unused.

Caution Overriding the default configuration limits can result in a low-memory condition.

The following sections describe the limits you can configure, default and maximum values, and commands for configuring and displaying the configuration limits:

•Static Route Configuration Limits, page 4-20

•IS-IS Configuration Limits, page 4-20

•OSPFv2 and v3 Configuration Limits, page 4-21

•Routing Policy Language Line and Policy Limits, page 4-23

•Multicast Configuration Limits, page 4-24

•MPLS Configuration Limits, page 4-25

•Other Configuration Limits, page 4-25

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.
