Summarising the few private replies I've had:
* a few people did reply saying that they're using it successfully
* someone reported that it worked successfully on 12000 and some 7500 series
routers, running a 12.0S train IOS
* someone else reported that any IOS train that has been eligible to receive
"new features" in the last 9 months will have /31 bit PtP support
* I can add that vendor N's broadband concentrator doesn't allow you to
add a /31 (they actually let you assign up to /30, then /32 to an interface :)
I hope this is of some interest to the list members.
If anyone is running /31's on PtP links on vendor J's equipment, I'd like to
hear from you.
