Nexus 6K Layer 2 Data Center Interconnect using double sided vPC configuration

i Can anyone help I've got 2 DC's being connected by L2 Links. I'm planning to extend vlans between DC's

I know the 6000's don't support OTV and q n q tagging.

 

2 1gb layer 2 links that will be connected to Juniper Srx then into the N6Ks

 

Should there be 2 separate vpc's for each link with even vlans down 1 and odd vlans down the other for resilience and stp priorty and cost adjusted accordingly? is this supported?

Or is it better to have one VPC between both Cores?

how would you configure the port-channel for the resilience on the primary and backup interfaces?

conf t
switch(config)#
switch(config)# interface po xx
switch(config-if)#
spanning-tree port type network default
spanning-tree vlan 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30 port-priority 64
spanning-tree vlan 1,3-5,7,9,11,13,15,17,19,21 port-priority 112
spanning-tree vlan 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30 cost 4
spanning-tree vlan 1,3-5,7,9,11,13,15,17,19,21 cost 200000000

 

Kind Regards,

Hello Carl

 

I think the best option is utilize just one VPC. 

 

You could isolates the STP at each data center. Reference below.

Thanks for the reply i will investigate this further.
Kind Regards,
Carl
