I was playing a little with some show commands on ACI and i found that on leaves there are VXLAN tunnels also towards the APIC (10.0.0.1 in the figure); i was wondering why there should be these tunnels? APIC is using VLAN 3967 as infrastructure VLAN, and that's it. What's the meaning of those tunnels (in red in the picture)
Thanks for your answer
