[c-nsp] 6500 Physical Design..

[Mark Tohill]

Mike,

Thanks for that.

We're just hoping to upgrade a L2-only core comprising of stackable
switches, assorted.

The /30's to the edge routers makes sense.  I wonder what the pro's and
cons of L2 or L3 Etherchannel between switches? 

The problem is we only have single Sup720's in each Chassis i.e one Gig
RJ-45 port ready to use. Also have one 48-port 10/100/100 blade in each
chassis. Is there anything can be done to maximize
resiliency/convergence with the single Sup's i.e their connectivity?

Thanks,
Mark

Cross connect each gige of the router to each switch, the two switches 
to each other via gige/port-channel (l3 or trunk, which ever is more 
appropriate), put /30's between them, and run igp of your choice is 
gonna be the basic here i'd say knowing nothing about your environment.

Depends all on what you're planning on doing with the gear.  Turn up 
ospf, ldp, bgp, do some vrfs, get frisky with te tunnels... what exactly

are you attempting to accomplish?
