Overview/Description
Most complex networks include redundant devices to avoid single points of failure. Although a redundant topology eliminates some issues, it can introduce other problems. Spanning-Tree Protocol (STP) is a Layer 2 link management protocol that provides path redundancy while preventing undesirable loops in a switched network. This course identifies the problems that are caused by redundant switched-network topologies and the functionality of STP to prevent these problems. Routing is the process of determining where to send data packets that are destined for addresses outside of the local network. Routers gather and maintain routing information to enable the transmission and receipt of data packets. For traffic to cross from one VLAN to another, a Layer 3 process is necessary. This course describes the basics of inter-VLAN routing operations, including subinterfaces and router on a stick.
