ICND2 2.0: EtherChannel and Layer 3 Redundancy

This course is included in our On-demand training solution.


In hierarchical network design, some links between access and distribution switches may be heavily utilized. The speed of these links can be increased, but only to a certain point. EtherChannel is a technology that allows you to circumvent this restriction by creating logical links made up of several physical links. This course describes EtherChannel technology and the various technologies that are available to implement it. You will also learn how to configure EtherChannel and how to verify EtherChannel operations.
This course also explains solutions to routing problems in a local network with a redundant topology. One solution to these problems is explained through the router redundancy process. This course identifies HSRP, VRRP, and GLBP as Layer 3 redundancy protocols. The use of the show standby and show glbp commands are also covered.

Target Audience

Anyone wishing to obtain Cisco Certified Network Associate (CCNA) 200-120 certification that validates the knowledge and skills required to install, operate, and troubleshoot a medium-sized network, including connecting to a WAN and implementing network security. Interconnecting Cisco Network Devices Part 2 (200-101 ICND2) is an essential course for students preparing for the CCNA Routing and Switching certification or the ICND2 certification. Students pursuing the CCNA Routing and Switching certification should attend parts 1 & 2 of the ICND course. Network administrators, network engineers, network managers, network designers, and project managers. Familiarity with network fundamentals, implementing local-area networks, internet connectivity, managing network device security, implementing WAN connectivity and basic IPv6 connectivity is recommended.
