Abstract
Systems, methods, and computer-readable media are provided for securely advertising autoconfigured prefixes in a cloud environment. In some examples, a method can include, receiving, by a first router, an indication of an available network address prefix. In some aspects, the method can also include selecting, by the first router, a first network address prefix that is within the available network address prefix, wherein the first network address prefix provides at least one route to one or more network elements associated with the first router. In some cases, the method may further include sending, to a second router, a message including a stub registration option that indicates the first network address prefix.
