Gee, someone at Cisco had their thinking cap on. Let's hope Gert isn't
reading this, lest he vent-off about the 6500/7600 debacle (and rightly
so) :-).

Seriously though, crippling one box to help ship another has never sat
well with me. In the first instance, what business does a switch have
being a label switching router? Maybe I'm too purist, but when functions
begin to overlap like this, it's headache for operators and multiple
sources of revenue for equipment vendors, despite what their "portfolio
positioning" suggests. They are very aware about the confusion they are
causing, at our expense.

At least there are some new entrants into the space that haven't yet
been totally corrupted by the silo-based approach that leads to the same
company appearing like 1,200 different ones.

Yep, my point exactly.

Mark.
