SDA L2VNIDs

Hi All,

Quick question hopefully. I noticed that when DNA Center provisions a L2 network within a fabric site, its allocates a L2VNID starting 8188 for local segments and 16196 for multisite remote border/anchor VN segments.

If I remove and re-add an pool to a fabric site, the L2VNIDs are never reused and will increment from the last used. What is the range of the L2VNIDs that DNA Center allocates and what happens when this range is exhausted? Will DNA Center reuse any unallocated IDs?

Hi. The range is large, and Instance IDs will be reused if Catalyst Center reaches the end of the rage. Best regards, Jerome
