ICND1 2.0: WANs and Dynamic Routing Protocols

As an enterprise grows beyond a single location, it becomes necessary to interconnect LANs in various locations to form a WAN. Several technologies are involved in the functioning of WANs. This course describes the technologies, functions, and characteristics of WANs. Routing is the process of determining where to send data packets that are destined for addresses outside the local network. Routers gather and maintain routing information to enable the transmission and receipt of these data packets. Routing information takes the form of entries in a routing table, with one entry for each identified route. The router can use a routing protocol to create and maintain the routing table dynamically so that network changes can be accommodated whenever they occur. To effectively manage an IP network, you must understand the operation of dynamic routing protocols and the impact that they have on an IP network. This course discusses the need for routing protocols and describes the differences between interior and exterior routing protocols and also between link-state and distance vector routing protocols. The operation of link-state protocols is also explained. OSPF is an IGP that was designed by the IETF. Because OSPF is a widely deployed standard protocol, knowledge of its configuration and maintenance is essential. This course describes the function of OSPF and explains how to configure a single-area OSPF network on a Cisco router.

Target Audience
Interconnecting Cisco Network Devices Part 1 is essential for students preparing for the CCNA Routing and Switching or CCENT certifications. Students pursuing the CCNA Routing and Switching certification should complete parts 1 & 2 of the ICND learning path. Students pursuing the CCENT certification need only attend part 1 of the ICND curriculum. Anyone wishing to obtain Cisco Certified Network Associate (CCNA) 100-101 certification that validates the knowledge and skills required to successfully install, operate, and troubleshoot small to medium size enterprise branch network. Network administrators, network engineers, network managers, network designers, and project managers. Familiarity of navigating PC operating systems, the internet, and basic IP addressing knowledge skills recommended.
