Connector Vlan Schema (6513 Port Assignments)
|Connectors||VLAN ID||Connector||VLAN ID||Connector||VLAN ID||Connector||VLAN ID|
To create a VLAN for the Manhattan Landing Exchange Point, the two connectors who wish to communicate with one another would use the connector with the smallest numerical VLAN ID as the first digit and the second portion of the VLAN ID would come from the second connector with the larger numerical VLAN ID.
An example of this would be between Abilene with the VLAN ID of 01, and Surfnet with the VLAN ID of 13. The VLAN for these two connectors is 113. Another example for creating a VLAN between two connectors would be between Dante#3, whose VLAN ID is 03 and Nysernet whose VLAN ID is 06. The VLAN between these two connectors is 306.
To assign a VLAN ID for the Manhattan Landing Exchange Point is done by choosing the next number available. If we look at the current list of VLAN ID's the next number available is 15. The next network that connects to the Manhattan Landing Exchange Point would be given the VLAN ID of 15.
If you notice in the list there are "available" VLANs that were assigned at one time to a connector that is no longer connected to the Manhattan Landing Exchange Point. Those VLAN ID's are available for use, but this document is designed to explain how we derive at the next VLAN ID for a connector.
