BGP and OSPF
summary
Describes how IP routing finds destinations and copes with failures (e.g., a broken submarine cable), explaining that BGP handles inter‑organization path selection between autonomous systems and OSPF manages routing inside sites/areas. Shows practical reconstruction of routing on a home Linux box using the dn42 network, demonstrates software choices OpenBGPD, BIRD and Quagga, use of VPN virtual links between hackspaces, traceroute behavior, and a small playable network that actually routes traffic; gives concrete IPv4/AS size details (IPv4 is 32‑bit, /16 = 65,536 addresses).
