Cameron,

>     Gyan>  This topic has come up many times over the years in heated debate and this is another instance of that.  Agreed.  However, what makes this instance different is that we have a major problem to be solved with 4G  &  now as 5G is rolled out, segmentation is of utmost importance.  I think in the past we have not had a major problem to be solved and so this change being proposed did not gain traction,  but now as 5G becomes the "norm" as it will compete directly with broadband that customers will start using 5G in SOHO as well as other environments.   This is a major issue that has come up with the ramp up for 5G IPv6 only deployments.

It's difficult to design a better solution without understanding what "operational nightmares" mean.
Would you mind elaborating?
