N7k as redundant core with vpc to 4510/3750 as distribution switch

Hi - basic question here

Got 2 qty N7k as redundant core with vpc to 4510 and 3750 as redundand distribution switch running MST. I got stuck with some bad cabling design from our IDF to Datacenter so have 2 access switch whereby each one will have a etherchannel to both distribution 4510 and 3750. My question is this is  a doable design as I am not sure about the vpc upstream on how it effects etherchannel with MST for my distribution and access.

Thanks

Re: N7k as redundant core with vpc to 4510/3750 as distribution

vPC will be considered as one logical link by both upstream and downstream connected devices

the question here are you going to run L3 between the distribution and Core devices ? (  this is recommended design ) if yes, then you do not need to worry about MST and VPC if you going to have it L3 from distribution devices up to the Core

one thing to consider is the distribution switch in your design has big difference in terms of backplane throughput i mean between the 4500 and 3750 !

if you can have both as 4500 will be better and more consistent design

Good luck
