I am in the process of going through a core switch migration. Currently we run the 3 Tier model. 7k 5K 2K. We are using OTV as a DCI as well. We are exploring and want to go the VXLAN EVPN route. We have already purchased a bunch of 9k switches. 9332's, 93180's and 93108's. The plan would be use DCNM to manage the fabric.
Has anyone gone down this route? If so have you run into any major issues doing this? Can you please provide some general feedback as well as how this type of deployment is working for you?
