Hello,
So I'm new to VXLAN and been trying to set up a VxLAN lab, following the UDEMY course ' CCIE Data Center - VXLAN EVPN '.
I am really at a loss as to why show nve peers shows no peers on SW1 and SW2 despite the fact that I don't see anything else I'm missing.
See my network diagram, configuration and show commands below:
Any ideas?
