Enhanced Interior Gateway Routing Protocol #2 - EIGRP Startup Messaging

Previously we went over some of the big ideas behind EIGRP. In this video we will talk about some the initial messages exchanged between routers engaging in EIGRP. These will include HELLO, UPDATE and ACK. While we are at it, we will take a look at actual packet captures from an operating topology.Show more

From RFC 7868:
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.
