I have 6 sites all connected via a 20mb fiber ring. There is 1 dhcp server and wan connection at site1 and the netblock is 10.1.0.0/16 which is enormous. As you can tell all sites grab an IP from site1 and the only issue is when site1 goes down so do all of the sites.
What I want to do is introduce VLAN into the scenario and set the other 4 sites up with a separate neblock. This way we can move print servers, dhcp servers, etc to each location so if something goes down they can still function. Each switch in all sites have an IP of 1.1.X.3. What do you guys recommend? Should we make the current netblock small and reconfigure everything? (which is a lot of downtime) or should we take the next netblock after the /16 and create /24's for each site? Or maybe neither?
Also should the IP's of the other switches change? Thanks.
Thank in advance.
