Finally, after all the waiting and poking around there is now an official guide for using a Nexus 9300 as HW-VTEP for NSX. The recommended NX-OS release is: 7.0(3)I6(1) or later in same main release The supported VMware NSX release is: 6.3.3 and later on the same main release Here is the Link to the guide: https://www.cisco.com/c/en/us/products/collateral/switches/nexus-9000-series-switches/white-paper-c11-740091.html#_Toc502975411 I hope i have some time in the coming days to deploy it in my lab and test it. But after a first overview the guide look pretty forward.
Usually you don’t have to change the hardware forwarding mode on the Nexus 5600 from the standard cut through to mode. But if you want to run VxLan on them, you have to. The syntax to change the forwarding mode is pretty forward:
N5K1# sh run | inc hardware

I’ll go into detail for the last two ones. Delete it via REST API Right-Click on the object and “save-as” When you open…
After getting VXLAN F&L to work on the Nexus 9000v. I thought why not trying the “easier one”, which was already tested a lot of times over the last 1-2 years. And well, i works out of the box. How is it done? CSR1000v as Leafs IOU L3 Router (you can basically use any router that is capable of OSPF/ISIS/EIGRP and PIM) VPCS als clients to ping GNS3 to capture the Ethernet frames for a deeper understanding of what’s going on At first you need basic connectivity and dynamic routing in…
