BGP Configuration is always a big task to do. This Course has made it very easy for students to understand the BGP Concepts. It has many labs which will eventually make you comfortable working with BGP.
Border Gateway Protocol (BGP)is considered a “Path Vector” routing protocol. Itis an exterior gateway protocol (EGP) that is used to exchange routing information among routers in different autonomous systems.It is the only protocol which enables Internet to function. So it is very robust and scalable routing Protocol.
Once BGP peers form a neighbor relationship, they share their full routingtable. Afterwards, only changes to the routing table are forwarded to peers.
BGP metric is BGP attributes. It has3 tables, neighbor table, BGP table and Routing table. The AD (Administrative Distance)for eBGP routes is 20, iBGP is 200. It uses TCP-179. It'sPeers use incremental and triggered updates(5 sec interval for IBGP and 30 sec interval for EBGP). Ituses AS numbers to keep track of different administrative domains. 1-64511 are public, 64512-65535 are private autonomous numbers.
This course has many Labs which will make you very strong and comfortable in Implementing this protocol in your organization or at your home lab. You will get expertise on Attributes of BGPsuch as Weight, Local Preference, AS Path, MED , ORGIN and Communities. Since It runs the Internet, so we need a protocol which gives flexibility, that is why BGP is used. Only drawback is that It is extremely slow to converge.
Many more things like Route Reflectors, Confederation are also covered so that you get complete information about this BGP.
