Abstract

In some embodiments, an apparatus comprises a core network node configured to be operatively coupled to a set of network nodes. The core network node is configured to define configuration information for a network node from the set of network nodes based on a template, where the configuration information excludes virtual local area network (VLAN) information or IP subnet information. The core network node is further configured to send the configuration information to the network node.
