Abstract
A method for forming a communications network using routers. The first step is analyzing a router location to determine if the router location is VPN resource constrained or interface-constrained. The VPN resource constrained router network comprises at least at least two groups of routers and the same number of customer groups. The next step is connecting the first group of customers and routers, and the second group of customers and routers, using a round robin connectivity methodology and saving information in each router's database. The interface-constrained router network, comprises no more routers than the value [Q*], wherein [Q*] represents the number of routers that can be used by a group of customers so that VPN resources will not be exhausted faster than interface resources for the group of routers, then connecting customers to the group of routers using a round robin connectivity methodology and saving information in each router's database.
