ICND1 3.0: VLANs, Trunking, and Inter-VLAN Routing

Anyone, from junior to senior network administrators, who are responsible for the configuration, maintenance, verification, and troubleshooting of Cisco IOS Routers and Switches.


Expected Duration
181 minutes

You will be able to create and assign VLANs, implement Trunks, and deploy Inter-VLAN routing. This course describes the need for VLANs, Trunks, and Inter-VLAN Routing in modern day network deployments. It also provides best practice configurations for each.
