Abstract
In one embodiment, a provider edge packet switching device of a provider network is configured with different Internet Protocol (IP) forwarding information bases (FIBs) depending on whether the forwarding information base is associated with core-facing ingress packet traffic (e.g., packet traffic from the provider network) or customer-facing ingress packet traffic (e.g., packet traffic from a customer network). In the latter case of customer-facing ingress packet traffic, the customer-facing forwarding information base includes load balancing lookup results for load balancing traffic between a customer edge packet switching device and through the provider network. In the case of core-facing ingress packet traffic, the core-facing forwarding information base includes a lookup result for forwarding traffic to a customer edge packet switching device, and does not include the above-referenced load balancing lookup result information.
