Looking at the network drawing I made, there is a possibility that the VLAN from the last-mile provider enters our network on two different physical ports. The VLAN is put in the same EVPN instance.
The last-mile provider uses this so that we as the ISP are in control of migrating from one physical port to the other.
I'm wondering if this setup creates a loop, since an EVPN instance is sort of the same as a L2 switch. Or does EVPN have some sort of loop prevention built in?
