are the RRs, via an MPLS LSP for example. That latter is fine in many cases, the former is not. E.g. I would argue that a P-router can be an RR if desired.
There is no compelling advantage. No budget is too thin for 3 gray NPE-G1, if they are, maybe network engineers without borders can help you. There are some compelling disadvantages, my current and previous employer both have experienced VPN AFI BGP UPDATE crashing whole box (infact whole cluster of 3 VPN reflectors, at once). Trying to achieve 0 outages is silly and impossible, reducing outage impact is often simple and cheap, sometimes not done, when only failure modes considered are physical (HW, fibre, electricity...) failures, rather than the more common modes (pilot and software). -- ++ytti
