Introduction
Border Gateway Protocol (BGP) is the routing protocol that makes the internet work. In this post, we'll explore how to leverage BGP for building resilient enterprise networks.
Why BGP?
BGP provides path redundancy, traffic engineering capabilities, and seamless failover - critical for modern networks.
Implementation Strategy
Start with proper AS number allocation, then implement multi-homing with diverse carriers. Use BGP communities for granular traffic control.
Best Practices
- Always filter routes
- Implement prefix limits
- Use BGP communities
- Monitor route advertisements
Conclusion
BGP is powerful but requires careful planning and monitoring for optimal results.
