Abstract
CE devices of the present invention are enabled to make more judicious routing decisions in CE-based VPNs. In determining a next-hop in a path from a source CE to a destination subnet, CE-to-CE costs are associated with each next-hop CE in a plurality of next-hop CEs. Each CE-to-CE cost is a cost of a path from the source CE to the associated next-hop CE. CE-to-subnet costs are associated with each of the next-hop CEs. Each CE-to-subnet cost is a cost of a path from the associated next-hop CE to the destination subnet. Total-costs are associated with each of the next-hop CEs. Each total-cost is a sum of a CE-to-CE cost associated with a next-hop CE and a CE-to-subnet cost associated with the same next-hop CE. The next-hop in the path is set to be a next-hop CE associated with an associated total-cost.
