[c-nsp] Catalyst vs. Nexus

[Todd, Douglas M.]

Hey Nick:

So the 6500 is EARL7 and mpls runs in the ASIC, guess I don' understand the
difference between the EARL7 and EARL8.   Thought mpls on the 6500 was also
hardware is this why the 7K earl 8 does not completely support mpls like the
6500? Besided the idea of the 7K being a 6500 killer... :)

Why did they not make the 7K support pvst+ if the 5K supports it?  Guess moving
the RSPT is a better idea anyway.

Aggreed about the ospf interface style, make much more sense.

it's EARL8, so it's mpls capable at a hardware level.

The N5K supports pvst+:

That's a change for the better.  The IOS style ospfv2 configuration is all
wrong.
