Building Cisco Multilayer Switched Networks is a direct port of the official Cisco training class, providing students with an excellent self study tool or useful supplement to the actual class. It defines the Cisco-recommended campus network design, then provides an in-depth look at Layer 2 switching technologies such as Spanning Tree Protocol (STP), VLAN technologies, frame tagging protocols, VLAN Trunk Protocol (VTP), and Dynamic Trunk Protocol (DTP). Also, it covers Layer 3 routing services provided in the campus network, including inter-VLAN routing, Multilayer Switching (MLS) configuration, Hot Standby Routing Protocol (HSRP), and IP multicast configuration. Finally, it covers securing the switched campus network model, including setting passwords, local and remote login, modifying default privilege levels, and applying Layer 3 traffic management techniques to the campus network.
