(Note on my original post I avoided mentiong VyOS, because I was trying to talk generically since it was more of a theoretical concept that I wanted clarification on. Plus the vocabulary/concept is applicable to multiple vendors, I edited the post to specify that VyOS is the real product I'm inquiring about.)
