Configuration Limiting

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

Routing Process "ospf 100" with ID 0.0.0.0 Supports only single TOS(TOS0) routes Supports opaque LSA

It is an area border router

Initial SPF schedule delay 5000 msecs

Minimum hold time between two consecutive SPFs 10000 msecs Maximum wait time between two consecutive SPFs 10000 msecs Initial LSA throttle delay 500 msecs

Minimum hold time for LSA throttle 5000 msecs Maximum wait time for LSA throttle 5000 msecs

Minimum LSA interval 5 secs. Minimum LSA arrival 1 secs Maximum number of configured interfaces 255

The following example configures the maximum interface limit on a router:

RP/0/RSP1/CPU0:router# configure

RP/0/RSP1/CPU0:router(config)# router ospf 100

RP/0/RSP1/CPU0:router(config-router)# maximum interfaces 600

RP/0/RSP1/CPU0:router(config-router)# end

Uncommitted changes found, commit them? [yes]: y

RP/0/RSP1/CPU0:Mar 30 16:12:39 : config[65740]: %LIBTARCFG-6-COMMIT : Configuration committed by user 'cisco'. Use 'show configuration commit changes 1000000540' to view the changes.

RP/0/RSP1/CPU0:Mar 30 16:12:39 : config[65740]: %SYS-5-CONFIG_I : Configured from console by cisco

RP/0/RSP1/CPU0:router# show ospf

Maximum Routes Redistributed into OSPF: Example

In the following example, the maximum redistributed-prefixescommand is used to set the maximum routes redistributed into OSPF:

RP/0/RSP1/CPU0:router# configure

RP/0/RSP1/CPU0:router(config)# router ospf 100

RP/0/RSP1/CPU0:router(config-router)# maximum redistributed-prefixes 12000

RP/0/RSP1/CPU0:router(config-router)# end

Uncommitted changes found, commit them? [yes]: y

RP/0/RSP1/CPU0:Mar 30 16:26:52 : config[65740]: %LIBTARCFG-6-COMMIT : Configuration committed by user 'cisco'. Use 'show configuration commit changes 1000000541' to view the changes.

RP/0/RSP1/CPU0:Mar 30 16:26:52 : config[65740]: %SYS-5-CONFIG_I : Configured from console by cisco

A9KMOD80TR, A9K24X10GETR, ASR 9000 specifications

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.
