To summarize the issue we are trying to put to rest:

o All router-to-router links on the downstream side of an ITR use

Where is this assumption coming from?
As long as there are FastE links, this is not going to happen.

Are you trying to say that you currently have deployed
router-to-router links inside an ISP/IX with less than
4470 bytes of IP MTU ?

Btw, at least some 100baseTX/FX switches/routers can
support the 9180 IP MTU.  So it is not necessarily
the case that 100baseTX/FX implies a 1518 byte link MTU.
