Abstract
Methods, systems, and apparatus used to provide duplicate address detection in edge devices. Edge devices can include CMTS devices or DSLAMs where network nodes are not allowed to communicate with each other directly. Duplicate address detection proxies can provide duplicate address protection for network devices and can avoid the issue of broadcasting node advertisement messages to all of the devices connected to a particular downstream link.
