We are heading towards that type of deployment beginning next year with
Juniper EX4200 switches in a redundant configuration. This will be pure
Layer2 in nature on the switches and they will "uplink" to Juniper
M10i's for layer3... the power savings, space savings etc over
traditional Cisco 6500 chassis (plus all the cabling between cabinets
which is in our case a nightmare) made this a pretty easy choice... and
price too..;)
Somewhere on Juniper's website in the product info section they have
deployment whitepapers on this kind of stuff if that's of interest....
Hope this helps..
Paul

Guys,
I am wondering how many of you are doing layer 3 to top of rack switches
and what the pros and cons are. Also, if you are doing layer 3 to top of
rack do you guys have any links to published white papers on it?
Thanks,
Raj Singh
