    Example: Using Service Scopes to Customize Generic Services to Particular Regions

    You could use service scopes to customize a generic audio service called Audio-Bronze on a regional basis. This example assumes that the network is configured so that VR boston serves the Boston subnet and VR chicago serves the Chicago subnet.

    When the network starts operating, the SAE substitutes the parameters you specified in the service scope definition for the corresponding fields in the service subordinate to that scope.

    To customize the new service Audio-Bronze for the Boston and Chicago subnets:

    1. Add the Audio-Bronze service within a service scope called boston, and configure the IP address and mask used by VR boston in the parameter configuration.

      This IP address and mask determine an access point to the service provider’s equipment.

      user@host# edit services scope boston [edit services scope boston]user@host# edit service Audio-Bronze [edit services scope boston service Audio-Bronze]user@host# set parameter service-ip-address 10.10.40.33 [edit services scope boston service Audio-Bronze]user@host# set parameter service-ip-mask 255.255.255.255
    2. Add another Audio-Bronze service within a service scope called scope_chicago, and specify the IP address and mask used by VR chicago.
      user@host# edit services scope chicago [edit services scope chicago]user@host# edit service Audio-Bronze [edit services scope chicago service Audio-Bronze]user@host# set parameter service-ip-address 10.10.55.1 [edit services scope chicago service Audio-Bronze]user@host# set parameter service-ip-mask 255.255.255.255
    3. Assign service scope boston to virtual router boston.
      user@host# edit shared network device region_one virtual-router boston [edit shared network device region_one virtual-router boston]user@host# set scope boston
    4. Assign service scope chicago to virtual router chicago.
      user@host# edit shared network device region_two virtual-router chicago [edit shared network device region_two virtual-router chicago]user@host# set scope chicago
