Re: Is an xxUA SGP capable of serving multiple SGs

Barry,

I see your point.

According to your view an AS talks to one and only one SG within SGP,
that is, the AS sees (registers with) just one SG in the SGP and
cannot see more SGs served by the same SGP.

Have I got it right?

Is it a largely accepted view? I mean, are there SG products that do
that, since it does not put any additional requirements on the ASPs in
my view.

Thank you in advance

Ilie
