Join Greg Sowell for an in-depth discussion in this video Link state, part of Networking Foundations: Network Media (WANs).
- [Voiceover] Link State Routing Protocols…are more complex in nature,…though their basic functionality is fairly simple.…If distance vector is a road sign,…link state would be a full map.…Link state routers build a full map of the network…via advertisement sent from those neighbors.…Since each router has a clear view of the network,…it will independently calculate best path for itself.…A link state router will send information about its links,…its directly connected networks, and itself.…
Open Shortest Path First, or OSPF,…and Intermediate System to Intermediate System, or ISIS,…are examples of link state routing protocols.…Basic functionality starts by creating…a neighbor relationship with all neighbors…in the same layer two segment.…This is also known as forming adjacencies.…Each router sends link state advertisements that relay…information about the router itself and its links.…These LSAs are stored in a Link State DataBase.…
Once the link state database is built,…the Dijkstra algorithm is run to determine…
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).
