D. Savage: AUTHOR [+6]
This document describes the Enhanced Interior Gateway Routing Protocol (EIGRP), a routing protocol designed and developed by Cisco Systems, Inc. DUAL, the algorithm used to converge the control plane to a single set of loop-free paths is based on research conducted at SRI International . The Diffusing Update Algorithm (DUAL) is the algorithm used to obtain loop freedom at every instant throughout a route computation . This allows all routers involved in a topology change to synchronize at the same time; the routers not affected by topology changes are not involved in the recalculation. This document describes the protocol that implements these functions.

Cisco's Enhanced Interior Gateway Routing Protocol (EIGRP)
This document describes the protocol design and architecture for Enhanced Interior Gateway Routing Protocol (EIGRP). EIGRP is a routing protocol based on Distance Vector technology. The specific algorithm used is called "DUAL", a Diffusing Update Algorithm as referenced in "Loop-Free Routing Using Diffusing Computations" (Garcia-Luna-Aceves 1993). The algorithm and procedures were researched, developed, and simulated by SRI International.
