The ability to create VLANs on Layer 2 Ethernet switches is great for segmenting network traffic. However, a Layer 2 switch is not capable of routing traffic from one VLAN to another. Fortunately, we can use a single switch port connect to an external router, and let that router do the routing for us. This concept, called a “Router on a Stick” topology, is demystified in this video. The Router on a Stick Concept is a sample excerpted from Cisco CCENT ICND1 100-101 (Complete Video Course), a comprehensive, 17+ hour training course that brings Cisco CCENT exam topics to life through the use of real-world demonstrations, animations, live instruction, and configurations, making learning these foundational networking topics easy and fun.
