Cisco ROUTE 1.0: Connecting the Enterprise to ISPs
This course is included in our On-demand training solution.
The Internet has become a vital resource in many organizations, and the Border Gateway Protocol (BGP) is an alternative to using default routes to control path selections.
Before the connection of an enterprise network to an Internet service provider (ISP) can be implemented, planning needs to be completed. To plan for connectivity to an ISP properly, the network designer must take into account certain details. This course provides the knowledge required to implement enterprise-to-ISP connectivity. This includes an understanding of the types of session origination points those originating from the enterprise network or those originating from the Internet and the available routing options. It also provides the understanding to determine which routing option should be used in certain cases. Connectivity redundancy must also be considered.
This course describes the connectivity requirements between an enterprise network and an ISP, the exchanging of routing updates with an ISP, and the types of connections to an ISP. It also explains how BGP may be used by enterprises to connect to ISPs, and how BGP routes between autonomous systems, using path vector attributes, rely on routing policy decisions being enforced at the autonomous system (AS) level. The important terminology that is used in establishing BGP peering relationships, EBGP, and IBGP neighbors are defined. In addition, this course examines the difference between an IGP and BGP and explains the reason for having all routers in the transit path within an AS running IBGP.
