Then they were stupid.  You can take that with a grain of salt because
we don't own any of that stuff, but IPv6 has been out for what, the last
decade?  And your just now getting around to including it as a 
requirement in your RFPs?

Those orgs are just paying the deserved "stupid tax" IMHO.

Feel free to sling arrows, I'll listen to the sputtering justifications, 
but the fact remains you saved money by dropping what
should have been a mandated spec from your RFP 5 years ago when you
bought the stuff, and now your whining that they want more money.  Uh huh.

Yeah, well as an ISP, we have a few elderly 56K total control chassis
that only speak RIP also so we have run it too - but I certainly don't
run around -boasting- about it!
