Hi Ted, Here is the scenario that I am thinking might not be covered: 1) Router A (say your internet service provider) has an ISP interface with prefix 2001:: then has a ULA prefix for devices it is currently communicating with 2) Router B (in the same home connected via cellular) has a different ISP interface with prefix 2002:: and also has a different ULA prefix for a colleciton of devices it communicates with 3) Router A is now connected to Router B via an interface in the home (the join case). Obviously, one of them needs to be the owner of *the* ULA prefix in the home and the other should stop providing its prefix.
Same scenario for the split: 1) I have two networks that were joined with Router A and Router B linked. I decide to island one of my networks (for example, I have a lighting system using Router B but discovered there has been a security breach and I don't want it exposed to the internet through Router A). 2) Is it clear in terms of ULA prefix generation/propagation what Router A and Router B should be doing regarding forwarding prefix information on their internal (and by reference external interfaces)? Maybe this would be covered by the splits/joins topic but it does seem like ULA propagation changes in addition to the renumbering of the devices in the home using ULA prefixes.
