I'm building a new DataCenter and need help for solved a doubt with the proposal architecture (diagram attached). In layer 2 i have 3 N7k with fabricpath full mesh conected to five N5k, and vPC+ to 3 ASA5580 firewalls in cluster mode (9.1.4).
In layer 3 the firewalls are multiples context, each will be default gateway for different DC vlans and run ospf vs one vrf in N7k. For ospf peer adj in this zone ti's necesary removed the asa-n7k vlans interconection from vpc peer-link (in mode fabricpath) and stablish the ospf adjacencies for other dedicated non-vpc port-channel?. Are there any difference if we connect the firewall without vpc (port-channel for on firewall to one n7k)?.
In the external zone, the n7k connect with one router (two 6500 in VSS mode) with dedicated L3 interfaces, it's necesary other dedicated l3 interface for this zone?.

decision. To do this we require the switch to do...
