Join Greg Sowell for an in-depth discussion in this video Tunnels and VPN, part of Networking Foundations: Network Media (WANs).
- [Voiceover] Tunnels in virtual private networks…can be used in several situations,…but the most common is to connect…one remote resource to another over the Internet.…Tunneling and VPNs can connect remote sites…in much the same way as an MPLS or point to point connection…but for a fraction of the cost.…Tunnels can carry nearly any kind of traffic…from standard file sharing, voice, video to data collection.…The term VPN and tunnel are often used interchangeably.…
VPN generally implies a secured connection…for remote users and between remote sites.…Tunnels are also most often thought of…as site to site connections,…or methods to connect two or more remote locations together.…VPNs often imply remote user connections…where employees working abroad…will have a secure way to connect back into the network.…No matter the type of tunneling protocol you use,…they all take your packet and encapsulate them at your side…and send them across a network,…at which point they are decapsulated on the far side.…
Think of encapsulation as taking a message and…
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).
