I see you've been giving this advice for quite some time now.

We've been running all address families on the same RR's (different
sessions, obviously, but same hardware) for almost 5 years. The only
reason sessions have gone down is due to hardware problems. It didn't
disrupt services because there are always 2 RR's, but we haven't seen an
outage due to protocol problems in one address family spilling over into
other address families.

Of course, I see your concern, but from our own experience over several
years, I've not seen this issue.

I mention this because introducing this kind of separation is onerous.

Mark.
