ICND2 2.0: Interconnecting Cisco Networking Devices Part 2

This course starts with a review of VLAN and trunk technology. Understanding how VLANs and trunks operate and which protocols are associated with them is important for configuring, verifying, and troubleshooting VLANs and trunks on Cisco access switches. This course also addresses some of the common reasons that port connectivity, VLAN configuration, and trunk establishment can fail. It describes what information to look for to identify the source of the problem and determine how to solve it. Switched networks introduce redundancy, so an STP loop-avoidance mechanism is needed to prevent undesirable loops. Most complex networks include redundant devices to avoid single points of failure. Although a redundant topology eliminates some issues, it can introduce other problems. STP is a Layer 2 link management protocol that provides path redundancy while preventing undesirable loops in a switched network.
