1.7 Versioning and Capability Negotiation
Supported Transports: The RRAS Management Protocol uses the RPC protocol as a transport and the RPC protocol sequence as specified in section 2.1.
Protocol Versions: This protocol has three interfaces named DIMSVC, RASRPC, and REMRAS. Each interface has only one interface version. The interfaces have been extended by adding additional methods at the end. The use of these methods is specified in section 3.1, section 3.3, and section 3.5.
Security and Authentication Methods: Authentication and security for the transport used by this protocol are specified in [MS-RPCE]. For the RPC and DCOM interfaces, the security and authentication mechanisms are described in section 5.
Localization: This protocol passes text strings in various methods. Localization considerations for such strings are specified where relevant.
Capability Negotiation: The RRAS Management Protocol does not support negotiation of the interface version to use for the RPC interfaces. Instead, this protocol uses only the interface version number specified in the Interface Definition Language (IDL) for versioning and capability negotiation.
