VPC and Routing Design using BGP

Hi guys,

I have some doubts relating BGP routing over VPC. I have 1 pair of Nexus 5600 switches configured in VPC mode, and i need to know if is supported to have this config:

-1 Ebgp session between NexusA and a third party router (RouterA), using Nexus SVI interface. RouterA is only connected to NexusA

-Another Ebgp session between NexusB and another router (RouterB), using Nexus SVI interface. RouterB is only connected to NexusB

-An IBGP session between NexusA and NexusB to share routes leart from peer Nexus...here is really the point where i  am more confused, cause this ibgp peer session would need to cross vpc peer-link

-NexusA and Nexus B will be in same vpc domain, configured with "peer-gateway" and "layer3 peer-router" options

I have not seen specific documents or samples about a configuration like this one, please anyone can inform if is it supported?

Regards and TIA

Juan
