Randy, Ah, I don't know how that happened, but Ronald X-posted to Routing and I managed not to. Don't worry, we're not trying to steal their family jewels. 🙂 Brian Brian Nisbet (he/him) Service Operations Manager HEAnet CLG, Ireland's National Education and Research Network 1st Floor, 5 George's Dock, IFSC, Dublin D01 X8N7, Ireland +35316609040 brian.nisbet@heanet.ie www.heanet.ie Registered in Ireland, No. 275301.
