Learn how to assign IP addresses to VLANs on a Cisco switch to enable inter-VLAN communication and improve network segmentation. This guide provides a step-by-step walkthrough, including VLAN creation, port assignment, and IP configuration. If a second IP Range is required, and your 6500 has a Layer 3 supervisore engine, the best option here is to create another VLAN and implement routing between them as you see fit. Doing this is much much easier and will save you a major headache further down the road when your network begins to act. In this article, we gave IP addresses to four VLANs on switch S1: IT, HR, SALES, and GUEST. Devices in each VLAN can use the IP address as a gateway to connect inside the VLAN. Everything works fine, I can ping back to the router. I created the same VLANs on the second switch (which is trunked to first switch), but am wondering what to assign for IPs.
