Abstract:
1. A method of controlling access of network management requests directed to one or more network devices that participate in a virtual private network, the method comprising the computer-implemented steps of: receiving a request to carry out a management protocol operation; determining, in the request, an identifier of a virtual private network and a context name; determining, based on the context name, one or more sub-contexts that are either explicitly or implicitly specified in the context name; identifying, among a plurality of instances of managed objects that are associated with one or more routing topologies of a multi-topology routing system, a subset of object instances that requests associated with the virtual private network are permitted to access; and providing the request with access to only the subset of object instances; wherein identifying the subset of object instances is based, at least in part, on the one or more sub-contexts that are either explicitly or implicitly specified in the context name.
