Hands-on guidance for deploying and optimizing BGP networks–enterprise and ISP
Now there’s a practical guide to deploying and managing BGPv4 in any environment–from small enterprises to the largest Tier 2 and Tier 3 service providers. A team of the world’s leading BGP experts brings together powerful insights into network design, configuration, and deployment with the latest version of BGP–including hands-on guidance for leveraging its key enhancements. Coverage includes
• Best practices and diverse real-world scenarios for applying BGPv4
• Understanding the impact of BGP design on local networks and the global Internet backbone
• Building effective BGP policies: aggregation, propagation, accounting, and more
• Maximizing scalability and performance in BGPv4 networks
• BGP and network security, including Secure Origin BGP
• Deploying BGP/MPLS Layer 3 VPNs
• Extensive troubleshooting guidance unavailable in any other book
If you’re a network engineer or administrator looking to drive maximum reliability and performance from BGP-based networks, Practical BGP will help you get the job done–from start to finish.
