<div dir="ltr"><div>I ran stack.sh in one controller node and two compute nodes. Q_ML2_TENANT_NETWORK_TYPE in local.conf is set to vxlan in all nodes. after starting an instance, I saw the ovs configuration as follows. my question is why there are vxlan ports on both br-int and br-tun? if I send a packet from the instance, which path will it go?<br>
<br>1. "tape8f9588f-5e" -> patch-tun -> patch-int -> "vxlan-ac160965" and "vxlan-ac1f007d"<br>2. "tape8f9588f-5e" -> "vxlan-172.31.0.125" and "vxlan-172.22.9.101"<br>
