Depending on the model and Cisco IOS version, the commands available and the output produced might vary from what is shown in th e labs. Other routers, switches, and Cisco IOS versions can be used. The switches used in the labs are Cisco Catalyst 2960s with Cisco IOS Release 1 5.2(2) (lanbasek9 image). Note : The router s used with CCNA hands-on lab s are Cisco 4221 with Cisco IOS XE Release 1 6.9.4 (universalk9 image). In this lab, you will create VLANs on both switches in the topology, assign VLANs to switch access ports, verify that VLANs are working as expected, create VLAN trunks between the two switches and between S1 and R1, and configure Inter-VLAN routing on R1 to allow hosts in different VLANs to communicate, regardless of which subnet the host resides. A particular kind of inter-VLAN routing, called “Router-On-A-Stick”, uses a trunk from the router to the switch to enable all VLANs to pass to the router. Trunks allow the traffic from multiple VLANS to travel over a single link, while keeping the VLAN identification and segmentation intact. VLAN trunks are used to span VLANs across multiple devices. Routers in VLAN topologies provide additional security and traffic flow management. Communication between VLANs requires a device operating at Layer 3 of the OSI model.
In general, VLANs make it easier to design a network to support the goals of an organization. VLANs address scalability, security, and network management. Modern switches use virtual local-area networks (VLANs) to provide segmentation services traditionally provided by routers in LAN configurations.
