7. A method comprising:
accessing a connection configuration request for a user network, wherein the connection configuration request specifies a planned routing method for communication between the user network and a network service provider, wherein the connection configuration request includes a plurality of prefixes, and wherein each prefix of the plurality of prefixes includes one or more network addresses;
accessing a first data store, wherein the first data store includes utilization tracking data for prefix availability with respect to the user network and wherein the utilization tracking data is updated after each allocation of prefixes; and
based on the utilization tracking data and the connection configuration request, verifying at least one operational criterion is met for a plurality of routing resources by determining whether an intended allocation of prefixes to one or more virtual interfaces is within a threshold number of prefixes available to the user network.
