- BGP (Border Gateway Protocol): Path-vector protocol connecting Autonomous Systems (AS) via TCP port 179. Advertises IP prefixes with attributes like AS-PATH and LOCAL-PREF. - OSPF (Open Shortest Path First): Link-state interior gateway protocol (IGP) using Dijkstra's SPF algorithm to compute shortest internal network paths.
