Thus spake Randy Bush (randy@psg.com) on Tue, Nov 18, 2025 at 02:55:07PM +0900:
In our measurement/monitoring systems we do record the BGP router ID of every neighbor. This is handy as it should[*] be unique to an AS
uh, my memory is that the spec is that it is unique WITHIN an AS. two ASs can have routers with the same routerID.
doh! yes, typo on my part. Dale
