Hi.. I currently have two segments on my network:192.168.16.0/24 and 192.168.17.0/24 along with other routers and stuff that go to other places. The Cisco 3620 router routes between the segments and feeds switches dedicated to each segment. I have DHCP running and also use static IP addresses for about 70 servers and non dhcp capable pieces of equipment.
Here is the issue. I need to change the IP addresses of these segments to 172.29.112 and172.129.113 respectively.
Is there a way that I can sit the new segments right on top of the old segments and then change the Static IP addresses over without losing connectivity? I would imagine that I could then change over the static IP addresses to the new numbers then change dhcp in one fell swoop. If I just get a cheap router (or a quick linux box) to route between the segments, can I plug the 172.29.112.1 and 113.1 ports of the new router into the switch fabric of the old segments and route both segments appropriately?
