Now we are using class C ip addressing at head off & branches. All Branches are connected throught Lease Line with Head off. All Routers are using RIP1 for dynamic routing. Now host is going to increase more then 254 so we wants to change with Class C ip addressing scheme with Class B. We will use RIP2 for new setup. I am attaching the file for Class B IP Addressing, pls guide me. It will work properly na. what we need to reconfigure in router??? Waiting for urs reply.
