I have a cisco 861 router and have 4 subnets in which I would like to create vlans. But for some reason, I can only have 2 vlans on the router. I have done some research and have found that the 861 IOS is limited to 2 vlans. One of the suggested solutions was to get IOS software that includes Advanced IP Services. The question comes where can I get this IOS? Can I just download it from Cisco's site or is it something additional a need to purchase or am I just out of luck?
Please let me know, thanks.
