No. OSPF and IS-IS really works by communicating the network topology and then each node independently computing shortest path route selection.
But BGP (and also RIP and Babel) works by a distributed algorithm, where each node selects best routes for each destination from available routes received from neighbors, and announces selected best routes to neighbors.
- idorosen 5y agoIn networking parlance, BGP is a distance vector routing protocol, as opposed to link state routing protocols like OSPF.
