Interconnecting Cisco Networking Devices Part 1

Modul ICND 1

Interconnecting Cisco Networking Devices Part 1

ICND1: Interconnecting Network Devices, Part 1 is the first out of  two parts for network professionals to take to prepare for the Cisco Certified Network Associate (CCNA) exam.

Module ICND1 contains the curriculum of CCNA1 and CCNA2 modules.

ICND1 introduces students to basic concepts in network technologies and helps develop the skills needed to design and implement small networks.

One of the main topics of ICND1 is the issue of dynamic routing in computer networks. Participants will receive an overview of internal routing protocols such as RIPv2, EIGRP and OSPF. Each of the protocols is discussed in depth - from the basic working principles in the network to configuration. Consideration is also given to the basic concepts of routing redistribution. The scope of the module's topics is closed by DHCP and NAT services.
