Nexus 7K - Interconnect 2 Fabricpath Domains with dot1q trunk link

Need some advice about the design, will it work.

Please refer to attached diagram.

 

N7K-1 and N7K-2 interconnect on  port-channel 1 running fabricpath.

N7K-3 and N7K-4 interconnect on  port-channel 1 running fabricpath.

 

Host A on VLAN190 of N7K-1/N7K-2 need to communicated with Host B on VLAN190 of N7K-3/N7K-4.

Host A & B are on same IP subnet.

 

I design such that N7K-1 physical connected to N7K-3  with dotq trunk and allowed VLAN 190.

The same apply to N7K-2 to N7K-4.

 

1) Will spanning tree loop happen to VLAN 190?

2) Does this network topology design work ?

and any other advice.

 

Thanks.
