NX-OS loopback interface down (In the eve-ng environment)

[Translator]

Hi!

When I enable the VPC function, the loopback goes down. (nxosv9k-9.3.9 In the eve-ng environment)

It doesn't seem to go down under all conditions, but I'd like to know under what conditions loopback goes down when VPC is enabled.

If I activate VPC in the environment where I am practicing evpn vxlan, it seems to be down, but if not, it seems not to be down.. but I will share it here.

best regards,

What is the mac address of LO?

The mac address of system is change after config vpc'

You need to add feature first then add LO to NSK.

This my opinion.
