- [Voiceover] Enhanced Interior Gateway Routing Protocol…was introduced by Cisco in the early 1990's…to replace their aging IGRP implementation.…As of February 2013, Cisco submitted EIGRP to the IETF…to become an open standard.…EIGRP supports Variable Link Subnet Masks,…Classless Inter-Domain Routing,…it doesn't send periodic updates,…and has both plane-text and MD5 passwords.…
It uses protocol 88 to exchange routing information,…and can load balance over unequal cost paths.…EIGRP is an enhanced distance vector protocol,…or sometimes, called a hybrid protocol.…Its route table is disseminated…as a distance vector protocol,…but it has neighbors and uses hellos…in much the same way as a Link-state protocol.…Full updates are only sent as a router first comes up.…After that, only partial updates are sent as the topology…or metrics change.…
EIGRP is made up of four main components:…Protocol dependent modules,…neighbor discovery and recovery,…reliable transport protocol,…and the diffusing update algorithm, or DUAL.…Protocol dependent module refers to the fact that EIGRP…
He discusses different WAN technologies and features such as speeds, spans, and price points—including inexpensive options such as VPN. He then covers switches (the devices that connect computers in your building) and routers (devices that control the transmission of network data). Along the way, Greg shows how to build private connections, implement free networking over the Internet, build switch networks, and overlay-routed networks. He'll also introduce different routing protocols, such as OPSF link-state routing and distance-vector routing with RIPv2, EIGRP, and BGP.
Note that this course maps to domains 1 and 2 of the Microsoft Technology Associate (MTA) Networking Fundamentals certification exam (98-366).
