Description

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.
