Network Interconnection Over a Core Network

Abstract

According to one embodiment, a method includes receiving, by a first edge device at a first site, a first site overlay control plane message including control plane information. The first edge device translates the first site overlay control plane message into a core overlay control plane message. The first edge device sends the core overlay control plane message over a core network to a second edge device at a second site.

         14 . A method comprising:
 receiving, by a first edge device at a first site, a core overlay control plane message including device ID information from a second edge device at a second site over a core network;   storing the device ID information in an edge device memory; and   generating a device ID seed for a first switch device at the first site, the device ID seed being used to generate a device ID that is unique across the first site and one or more remote sites.   
     
     
         15 . The method of  claim 14  wherein generating the device ID seed comprises:
 generating the device ID seed based on at least one of a site ID associated with the first site, an IP address associated with the first edge device, or a preconfigured seed parameter. 
 
     
     
         16 . The method of  claim 14  wherein the device ID information relates to one or more remote device IDs associated with one or more remote devices, and wherein generating the device ID seed comprises generating the device ID seed based at least in part on the device ID information so that the device ID generated from the device ID seed will not collide with the one or more remote device IDs. 
     
     
         17 . The method of  claim 14  wherein generating the device ID seed occurs in response to one or more of the following events:
 connecting a device to the first site; 
 rebooting a device at the first site; 
 reconfiguring a device at the first site; and 
 identification that a device ID associated with a device at the first site is not unique across the first site and one or more remote sites. 
 
     
     
         18 . The method of  claim 14  wherein the first edge device is configured to execute a device ID conflict resolution process if a device ID collision is detected.
