I have in my with one of my clients “C” Class network. Now that the number of computers have crossing 255 I need to advice them setting up a Supernet. My Client has Nortel ARN Router, Nortel Coreswitch(passport 8606) and Nortel Edge Switches. The client looks at increasing the number of IP’s. Can I suggest them to use a supernet 255.255.248.0 and who can do I configure them? Do i need to use the router to route the subnets or can I use the Core switch and create a route table with one single supernet for the IP?
