| 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.
