[j-nsp] EVPN VGA MAC address learning cause flooding

Hi! Experts

Sorry for disturbing, I am curious why IRB interface in EVPN does not use
VGAs' Virtual MAC address (00:00:5e:00:01:01)  to originate packets,  but
instead uses the interface real MAC address to originate packets.

Are there any special thoughts behind this? It will cause BUM flooding if
peer is a layer 2 switch ( peer s will never learn VGA virtual MAC address)

Thanks for your help!
