We have about 40,000 nodes on our network. As of late the discussion of implementing Wireless networking campus wide has come up. We are looking at many ways to do this. One is to create a separate flat network just for wireless so people can roam from building to building without rebooting or having to get a new address. The other is using Mobile IP in 6 months when it comes out. From what I know of Mobile IP I think that it will be a support nightmare. But that is just my opinion. My real question is what does everyone think of Supporting Mobile IP in a large network?
