I have the following topology.
I have four QFXs connected via EVPN/vXLAN. The dotted lines show the peer relationship. Based on my understanding, with the red line, a possible loop could occur. Without the red line, no loop could occur. Am I right ? As the BUM traffic advertised to the peer vtep would not be forwarded to other VTEPs. Right ?
With the Red line, A BUM from VTEP-3 might be learnt by VTEP-4 via the Red line, the loop then occurs. Right ?
thanks for your insights and coaching !!
