[c-nsp] Cat6500 - Support for MPLS and IPv6

[Juno Guy]

btw, you forgot ION (aka Modularize IOS)  ;-)

I to dont mean to sound like I am on the attack on Cisco but I, like many of
you, have been continuaously bitten by the need to upgrade and upgrade just
to fix my first upgrade if you follow me.  I will say that the different IOS
idiosyncrasies and OS made sense for them at one point.  If they hadnt done
what they did and adjusted/accomodated their customer requirement they very
likely wouldnt off been the dominant vendor today (or atleast not as fast).
I however think that they are way to far now to fix IOS in its current way
and as a result they have to put out a new OS (or a few of them).

Again, when you look at Juniper what they had was hindsight to know what not
to do in order to meet the requirements of NGN (SP and Enterprises) and they
have been extremely disipline about not taking the Cisco approach.

Cisco now on the other hand is combating diversity vs. focus and sooner or
later you will be affected by one or the other.  They are to big to just
look at one without the other because at the end of the day they (more so
than others due to their size) cant afford to lose any existing revenue and
most find new ways to please the shareholders.

You have to ask why did Cisco decide to move forward with NX-OS when IOS-XR
was suppose to be their next gen "modular" OS?  What is wrong with IOS-XR
that it wasnt good enough for "DC3"?
