Re: Design issues: Inter-connecting Nexus 5000 switches

Mish,
to my knowledge there is no need to interconnect access switches to benefit
from vPC. Please check out this document "Data Center DesignIP Network
Infrastructure" to validate your design. Though it says "IP network
infrastructure", it covers L2 topologies as well, and fairly good explained.

You can also check a series of chapters starting from this
