Join Greg Sowell for an in-depth discussion in this video BGP, part of Foundations of Networking: Network Media (WANs).
- [Voiceover] Border Gateway Protocol is the core…dynamic routing protocol for the internet.…BGP's current version four,…has been in use since 1994.…BGP is considered a path vector routing protocol.…While most routing protocols look at their networks…as hopping from router to router,…and finding the best paths to traverse, a few routers away,…BGP looks at the big picture.…Instead of router to router, it looks at networks as…autonomous systems to autonomous systems.…
An AS is a conglomeration of routers…defined within a company's control.…This could be one router or a 1,000.…These ASes are defined by an AS number.…An ASN is a 16 bit number providing…65,536 possibilities.…ASN zero is reserved for nonroutable addressing.…And 64,512 through…65,534…are reserved as private ASNs.…
A private ASN can be used inside any network…as long as they are removed from the AS path of routes…advertised to the internet.…Interdomain routing consist of two parts.…An address prefix and an ASN.…Each prefix is sourced from an ASN,…better known as an origin AS.…
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).
