Setup Requirements Static S-PE selection and PSN tunnel selection MUST be provided. The MS-PW path MUST have the ability to be dynamically setup between the U-PEs by provisioning only the U-PEs. Dynamic MS-PW pseudo wire setup requires that a unique identifier be associated with a PW and that contains sufficient information to determine the path to the remote U-PE Procedures MUST be provided to allow dynamic setup of MS-PWs across providers when the providers do not advertise IP reachability information to routers in their network Solutions MUST strive to minimize amount of configuration to setup an MS-PW. MS-PW signaling procedures MUST define clear rules for triggering the setup of segments of a MS-PW. The signaling procedures MUST be defined such that the setup of a MS-PW is considered successful if and only if all segments of the MS-PW are successfully setup. Mechanisms MUST be developed to propagate setup explicit failure indications to the S-PEs and U-PEs associated with the failed MS-PW. |
