The network configuration may involve any of the following technologies:
IP routing protocols
MPLS signaling protocols
Creation of LSPs
User-defined DiffServ classes of service
All of the above can be set up using the device-level EMS. Alternatively, the NMS user can specify the required configuration to generate the associated EMS scripts automatically. Another NMS scheme might involve the user interacting with a graphical topology map, clicking node-specific software options to select the appropriate setup.
Regardless of the setup method, the operator must carry out a fairly detailed set of steps to arrive at the situation depicted in our sample MPLS network.
