Openstack traffic flow is not showing on patch-tun or patch-int

I´m analyzing OpenStack traffic flow between instances, to understand how the traffic goes from one place to another. I have a provider network with openvswitch configuration. My scenario is depicted in the photo, where I make a ping between two machines in the same network but in different compute nodes.

I currently can see using tcpdump the traffic flowing between the tap and qvb interface in the qbr bridge:

root@compute3:/home/mw# tcpdump -i tape0109961-57 -p icmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on tape0109961-57, link-type EN10MB (Ethernet), capture size 262144 bytes
10:01:20.647598 IP 192.168.200.184 > 192.168.200.211: ICMP echo request, id 6, seq 5860, length 64
10:01:20.647874 IP 192.168.200.211 > 192.168.200.184: ICMP echo reply, id 6, seq 5860, length 64

root@compute3:/home/mw# tcpdump -i qvbe0109961-57 -p icmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on qvbe0109961-57, link-type EN10MB (Ethernet), capture size 262144 bytes
10:01:32.663739 IP 192.168.200.184 > 192.168.200.211: ICMP echo request, id 6, seq 5872, length 64
10:01:32.664067 IP 192.168.200.211 > 192.168.200.184: ICMP echo reply, id 6, seq 5872, length 64

And also can see the traffic arriving at the qvo interface on the integration bridge on openvswitch using ovs-tcpdump:

root@compute3:/home/mw# ovs-tcpdump -i qvoe0109961-57 -p icmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on ovsmi969443, link-type EN10MB (Ethernet), capture size 262144 bytes
10:04:56.929662 IP 192.168.200.184 > 192.168.200.211: ICMP echo request, id 6, seq 6076, length 64
10:04:56.929849 IP 192.168.200.211 > 192.168.200.184: ICMP echo reply, id 6, seq 6076, length 64

But I can't see the traffic flowing for the patch-int or patch-tun interfaces, however, when I capture traffic on the vxlan interface, the traffic is flowing there:

root@compute3:/home/mw# ovs-tcpdump -i vxlan-ac100186 -p icmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on ovsmi181239, link-type EN10MB (Ethernet), capture size 262144 bytes
10:06:50.080366 IP 192.168.200.184 > 192.168.200.211: ICMP echo request, id 6, seq 6189, length 64
10:06:50.080620 IP 192.168.200.211 > 192.168.200.184: ICMP echo reply, id 6, seq 6189, length 64

So, am I missing something? Where is the traffic flowing to reach the vxlan interface and go through the overlay network? I capture in both computes nodes and the result is the same. If someone knows why this is happening, I will thank the help.
