Selective Update Protocol (SUP)

Q: What is Selective Update Protocol?

Selective Update Protocol (SUP) is a routing protocol behavior in which a router sends updates only about routes that change, rather than transmitting a full routing table on every update interval. Expanded Explanation 1. Technical Function and Core Characteristics SUP describes a mechanism, used most notably in distance-vector routing protocols such as Routing Information Protocol version 2, where routers advertise only changed routing information after the initial table exchange. This

Selective Update Protocol is a routing protocol behavior in which routers advertise only changed routes instead of sending full routing tables every interval, which reduces control-plane bandwidth usage and influences convergence and capacity planning in enterprise network designs.
