Description
Introduction to the 4 Ports Router
The ASR5K-C4OC3-SM-K9 is a Cisco ASR 5000 Channelized Line Card 2 (CLC2) designed for the Cisco ASR 5000 Series Router. This line card is a 4-port router that supports OC-3/STM-1 interfaces, which are commonly used in service provider networks. The Cisco ASR 5000 Series is a high-performance, reliable and scalable edge routing solution, specifically designed for service providers and enterprises.
The ASR5K-C4OC3-SM-K9 provides a number of benefits over traditional edge routing solutions, including increased density and reduced cost of ownership. By supporting channelized OC-3/STM-1 interfaces, service providers can increase the number of interfaces in a single router, reducing the need for additional equipment. Additionally, it also support advanced features like Quality of Service (QoS), multicast, and security. QoS allows to prioritize certain types of traffic, such as voice or video, ensuring that they are delivered with the appropriate level of performance. Multicast allows for efficient delivery of data to multiple recipients at the same time. Security features like firewall and VPN support are also provided, which help to protect the network from unauthorized access and malicious attacks.
Routing Protocols and Configuration
The ASR5K-C4OC3-SM-K9 Cisco ASR 5000 CLC2 Channelized 4-Port Router supports a variety of routing protocols, including Border Gateway Protocol (BGP), Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), and Routing Information Protocol (RIP). These protocols allow the router to exchange routing information with other routers in the network and make routing decisions based on that information.
To configure the ASR5K-C4OC3-SM-K9 router, you will need to access the command-line interface (CLI) using a console or remote access method such as Telnet or SSH. Once logged in, you can enter commands to configure various aspects of the router, such as interfaces, routing protocols, and security features.
For example, to configure BGP on the router, you would first enable the BGP feature by entering the command “router bgp [ASN]”. Then, you would configure the BGP neighbors by entering the command “neighbor [IP address] remote-as [ASN]”. You would also configure the router’s own ASN and the networks it should advertise via BGP.
Similarly, to configure OSPF on the router, you would first enable the OSPF feature by entering the command “router ospf [process-id]”. Then, you would configure the OSPF interfaces by entering the command “network [IP address] [subnet mask] area [area number]”.
Quality of Service (QoS) Capabilities
The ASR5K-C4OC3-SM-K9 Cisco ASR 5000 CLC2 Channelized 4-Port Router supports a variety of Quality of Service (QoS) capabilities to ensure that different types of traffic are delivered with the appropriate level of performance.
One of the main QoS features supported by the ASR5K-C4OC3-SM-K9 is Class-Based Weighted Fair Queuing (CBWFQ). CBWFQ allows you to assign different traffic classes to different queues, and assign different weights to each queue. This allows you to prioritize certain types of traffic, such as voice or video, over less critical traffic, such as file transfers or web browsing.
Another QoS feature supported by the ASR5K-C4OC3-SM-K9 is Low Latency Queuing (LLQ). LLQ is a variation of CBWFQ that allows you to assign a priority queue for real-time traffic, such as voice and video. This ensures that real-time traffic is delivered with minimal delay, reducing the risk of jitter and packet loss.
Additionally, the ASR5K-C4OC3-SM-K9 also supports other QoS features such as:
- Traffic shaping: Allows you to control the rate of traffic flow, preventing congestion and ensuring predictable performance.
- Policing: Allows you to control the rate of traffic flow, discarding packets that exceed the specified rate.
- Link fragmentation and interleaving (LFI): Allows you to fragment large packets and interleave the fragments with small packets, reducing the risk of delay and jitter.
