    I have the following topology:
    The dotted lines shows the iBGP peering for EVPN/vXLAN.  Based on my understanding, without the red line, no loop would occur. As the BUM traffic advertised to the peer vtep would not be forwarded to other vteps.

    With the red line, a loop could occur. As the BUM traffic learnt from VTEP-3 might be forwarded to VTEP-4 via the red line, then it will be advertised back to the original vtep.

    Am I right  or anything I have missed ?

    With the red line, what are the best way to prevent the loop?

    thanks for any insights and coaching !!!
