DCNM 11.2(1) - Easy Fabric Template - vPC Peer Link VLAN

[AndyK1]

Hi there,

I have deployed DCNM 11.2(1) and attempting to use the Easy Fabric Template to use DCNM to manage a brownfield EVPN deployment which is in a lab. 

I am confused with vPC Peer Link VLAN - "VLAN for vPC Peer Link SVI"  (screenshot attached)

There is no SVI?  The vPC Peer Link is a trunk which carries vPC VLANs which are tagged on the port-channel.  Currently in my Lab there are no VLANs/SVIs besides a native VLAN.  My vPC peer-keepalive is via the OOB MGMT in the management VRF.

Thanks

I have the same issue, did you manage to figure out what is vPC Peer Link VLAN?
i tried with the VPVC trunked VLANs but it complains anyway

Hi All,

I met the same problem.

After a few hours test, I think I find a solution.
The setting in the vPC part of the fabric setting on DCNM means what SVI you would like to use to establish OSPF between vPC members.
By default, it uses VLAN 3600.
So, please try to create VLAN 3600 on both switches and enable OSPF on them.
Maybe no need to enable OSPF, I think this would be done automatically. (Haven't tested it)

After that, try to deploy it again and it should work.

For your reference,
vPC-peer1
