Command

Purpose

Step 4

 

 

ML_Series(config-if)# ip address

Configures IP addresses on routed interfaces.

 

ip-address ip-address-subnet-mask

 

Step 5

 

 

ML_Series(config-if)# end

Returns to privileged EXEC mode.

 

 

 

To enable and configure IRB and BVI, perform the following procedure, beginning in global configuration mode:

 

Command

Purpose

Step 1

 

 

ML_Series(config)# bridge irb

Enables IRB. Allows bridging of traffic.

Step 2

 

 

ML_Series(config)# interface bvi

Configures the BVI by assigning the number of the

 

bridge-group

corresponding bridge group to the BVI. Each bridge

 

 

group can have only one corresponding BVI.

Step 3

 

 

ML_Series(config-if)# ip address

Configures IP addresses on routed interfaces.

 

ip-address ip-address-subnet-mask

 

Step 4

 

 

ML_Series(config-if)# exit

Exits the interface configuration mode.

Step 5

 

 

ML_Series(config)# bridge bridge-group

Enables a BVI to accept and route routable packets

 

route protocol

received from its corresponding bridge group.

 

 

Enter this command for each protocol that you want

 

 

the BVI to route from its corresponding bridge

 

 

group to other routed interfaces.

Step 6

 

 

ML_Series(config)# end

Returns to the privileged EXEC mode.

Step 7

 

 

ML_Series# copy running-config

(Optional) Saves your configuration changes to

 

startup-config

NVRAM.

15310-CL, 15310-MA specifications

Cisco Systems has established itself as a leader in the networking domain, offering a wide array of solutions to meet the needs of modern businesses. Among its impressive product lineup are the Cisco 15310-CL and 15310-MA routers, designed to provide advanced network performance and reliability.

The Cisco 15310-CL is a versatile platform that primarily serves as a carrier-class router aimed at supporting high-speed data and voice services. It is built to handle the demands of large enterprises and service providers, offering a robust design that ensures maximum uptime and performance. One of its standout features is its modular architecture, which enables users to customize their configurations based on specific application needs. This scalability allows for future expansion without the need for a complete hardware overhaul.

Key technologies integrated into the Cisco 15310-CL include high-density Ethernet interfaces and a comprehensive suite of Layer 2 and Layer 3 protocol support. The device is capable of supporting multiple types of connections, including TDM, ATM, and Ethernet. This flexibility makes it an ideal choice for organizations that require seamless migration between various service types. Moreover, with features such as MPLS (Multiprotocol Label Switching) support and advanced Quality of Service (QoS) mechanisms, the router ensures that critical applications receive the necessary bandwidth and low latency required for optimal performance.

In contrast, the Cisco 15310-MA focuses on access solutions, providing a cost-effective entry point for businesses looking to enhance their network capabilities. It is well-suited for smaller offices or branch locations that need reliable connectivity without the expense and complexity associated with larger systems. The device supports a range of access methods and provides essential features like firewall capabilities, VPN support, and comprehensive security measures to protect sensitive data.

Both models benefit from Cisco's commitment to security and manageability, offering features like enhanced encryption protocols and user authentication mechanisms that help safeguard networks against threats. Additionally, they can be managed through Cisco’s intuitive software tools, simplifying configuration and monitoring tasks for IT administrators.

The Cisco 15310-CL and 15310-MA are ideal solutions for businesses seeking to enhance their network infrastructure, ensuring firms can keep pace with evolving technology demands while maintaining a focus on security and performance. Their combination of advanced features, modular capabilities, and robust support makes them valuable assets in the networking landscape.
