How the internet routes traffic between networks. BGP fundamentals, ASNs, peering, transit, route filtering, and RPKI security.
What Is BGP?
How BGP routes traffic between autonomous systems to make the internet work.
6 menit bacaASN Numbers Explained
How Autonomous System Numbers are allocated and used in internet routing.
4 menit bacaInternet Peering & Transit
How ISPs and networks exchange traffic through peering agreements and transit providers.
5 menit bacaBGP Route Filtering & Prefix Lists
Learn how BGP route filtering prevents route leaks and hijacks using prefix lists, AS-path filters, and IRR-based filtering.
11 menit bacaRPKI: Securing BGP with Route Origin Validation
How Resource Public Key Infrastructure (RPKI) prevents BGP hijacking by cryptographically validating which ASes are authorized to originate prefixes.
