https://community.extremenetworks.com/t5/extremeswitching-vsp-fabric/secondary-i-sid/m-p/8705#M286 Does the VSP platform offer any way to migrate from one I-SID to another I-SID?<BR /><BR />The intended use case would be for engineers that inherit an environment that they would like to standardize, or if there was an issue with an out of order I-SID scheme.<BR /><BR />I think the easiest way to do this would be to add some form of secondary I-SID functionality that way all BEB/BCB can pre-compute their connections for the given I-SID, which would then allow you to gracefully migrate all nodes off of the primary without service interruption?
