^ This is the important point I think.

Most networks I have worked on have/had RRs, but not all. And both scenario=
s have pros and cons. I just wanted to provide some data points about full =
meshes because, I think that every network I've worked on with RRs, had RRs=
 not because it was well thought out and clearly the best thing to do for t=
hat network, they had RRs because earlier someone just assumed RRs were nee=
ded.
