Absolutely -- that's my point. I'm surprised by bringing a new
software model to the 2T given that it's game over for the 6500.
However, given the effort, XE makes the least sense. (Unless the
"userland IOS" encapsulation is relatively easy, in which case I
would have expected it on high-end ISR's first).
Well... just because something is easy for Cisco doesn't mean they
would do it. They might believe that IOS XE on the ISRs would eat into
the market for ASR, so they don't do it.
Basically, I don't think we can infer anything about how easy or hard
IOS XE on the Sup2T would be. I suspect it wouldn't be hard to get it
running, but it might be to get it running fast.
I do share the original scepticism re: XE on sup2T, given past 6500
software shenanigans!
Well I think the deal breaker was PoE. They don't have a high density
modular platform with the install base of the 6500. If they would have
discontinued 61xx support in Sup2T, tons of customers would have
flipped. Oh, my migration options are 4500 or vendor x, y or z?
That would have put all the nails in the 6500 coffin.
But, I wish they would have spent the time to have the card support but
use a real OS. :(
