Episode notes
What Is BGP Routing Policy?
- Routing policy sets the rules for how networks exchange routes in BGP, including import and export filters.
- Without proper policy, networks could unintentionally become transit providers, causing widespread issues.
AS7007 Incident Teaches Routing Lessons
- In 1997, AS7007 incident involved an ISP misconfiguring routes, which propagated incorrect announcements and disrupted the internet.
- This historic event showed the importance of filtering and proper routing policies to prevent hijacks.
Enterprise vs Service Provider Policy
- Enterprises usually do not act as transit and prioritize redundancy when designing routing policies.
- Their BGP policy typically filters carefully what they announce and accept, differing from service providers' transit policies.
