Hi What is said is true for an individual VTEP that there is a 1:1 mapping between the VLAN and the VNI but in a VXLAN fabric, you can have different VTEPS with different VLANs be mapped to a same VNI. For instance, VLAN 100 on VTEP-1 can be mapped to VNI 10000 and VLAN 200 on VTEP-2 may be mapped to the same VNI 10000. thats how you can scale within the fabric.  Also, there might be future enhancements that might allow more VNI's on a single VTEP.   ...

Hi Sorry for the late response. Been busy with Cisco Live and other work, so couldnt reply you early. As mentioned before, you can only have 1 L3 VNI per tenant and multiple L2 VNI's. If you are having a multi-tenancy environment, then you need to create separate L3 VNI's for each Tenant. Please let me know if you have any other questions or if that answers your question.   ...

To fix this, you need to use the scp image compacting feature, the local image compacting is not supported.: https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus3000/sw/release/70372/n3k_70372_nxos_rn.html#_Toc498583962 Please do it “on the fly”, when downloading the image to the switch from its CLI via SCP, the compact option with copy command is allowed only with SCP protocol, the command is: switch# copy scp:<source image name> bootflash:<image name> compact vrf <vrf name> Note: if you already have the image on the bootflash, you’ll have to delete it first for the above command to work. Hope this helps  ... View more
