Cisco ICND2 1.1: Spanning-Tree Protocol and Inter-VLAN Routing

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


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.

Target Audience

Anyone wishing to obtain the Cisco Certified Network Associate (CCNA) certification that validates the knowledge and skills required to successfully install, operate, and troubleshoot small to medium size enterprise branch network. Network administrators, network engineers, network managers, network designers, and project managers. Candidates who have completed the 640-822 Interconnecting Cisco Networking Devices Part 1 (ICND1) exam associated with the Cisco Certified Entry Network Technician certification which is the first step in achieving the Cisco Certified Network Associate certification.
