Then each Access Island could have the same VLAN configuration (mirror configuration). The one-hundred level VLANs (200,
300 etc.) could be for testing with the prefix TEST.
Note: When provisioning with Profiles for each Access Island, the only Profiles that are unique to each Access Island are the General
Profiles, since the General Profile contains the VLAN and L3 static route information. The other Profiles (for service types) are
usually the same for RGs in any Access Island since the service offered would have the same attributes.
7.2.2.2 Multiple ISPs (Open Access)
In networks where there are multiple service providers for various services, each VLAN may be used for a service type and ISP. The
result is a set of VLANs for each service type, as shown in the following figure.
Refer to 7.9 for details on the multiple ISP configuration.
Note: The default is the Access Island model.
