• Failure to set up a full tunnel mesh for VM in a tier shall result in VM deployment failure.
• Failure to setup one or more bridge of the VPC, in full-connected mesh topology shall result in logical router to be disabled

Convergence time

Following are the events that require state update of configuration and corresponding latency: 

• Latency to replicate configuration is proportional to  (n*(n-1))/2 * m where  n is the number of hosts on which VPC spans and m is the number of tiers in the VPC. n*(n-1)/2

Architecture & Design description

...

• hosts on which a network (for tier in VPC) spans
• hosts on which VPC spans (cumulative of host on which individual tier's in VPC spans)
• list of VPC's that span on the host
