Abstract
Systems and methods are provided for generating a network ingress filter based on both a customer's route object and recent traffic data for the customer. In examples, even though a customer of a provider network may have many routing prefixes in its route object, the customer may genuinely generate traffic from only a very small percentage of such prefixes. Accordingly, a combination of a system to generate all the prefixes based on a route object, along with the results of collected traffic data, may be used to generate a much smaller ingress filter. In examples, this filter may comprise an intersection of the prefixes generated by the customer's route object and the prefixes that have been actively generating traffic on the inbound interface of the router (or other provider edge system). This results in a smaller ingress filter that can be reliably configured on the provider edge system.
