Hello Stackers Deployed OVN with Provider network on minimal setup with 3 controllers & 3 compute nodes. We are not using tenant network (only one external network ) for each vlan 2 & Vlan 8 Below is the ping behaviour for vms spread across two hypervisor (different networks ) VM1: 172.168.2.20 (vlan 2 )- SRC-Hyp VM2: 172.168.3.21 (vlan 8 )- Dest-Hyp Source Hypervisor: root@SRC:~# ovs-tcpdump -i patch-br-int-to-provnet-c24e134d-1a3c-4733-941e-0de548325497 icmp tcpdump: verbose output suppressed, use -v[v]... for full protocol decode listening on ovsmi688947, link-type EN10MB (Ethernet), snapshot length 262144 bytes 15:41:25.900113 IP 172.168.2.20 > 172.168.3.21: ICMP echo reply, id 18, seq 1, length 64 Dest Hyp: root@DEST:~# ovs-tcpdump -i patch-br-int-to-provnet-d33f01e8-6fe9-4597-998c-f6e339ba6386 icmp tcpdump: verbose output suppressed, use -v[v]... for full protocol decode listening on ovsmi853421, link-type EN10MB (Ethernet), snapshot length 262144 bytes 15:41:25.899394 IP 172.168.3.21 > 172.168.2.20: ICMP echo request, id 18, seq 1, length 64 This is first time with OVS, trying to understand below behaviour why we are seeing echo reply on patch-br-int-to-provnet-c24e134d-1a3c-4733-941e-0de548325497 ? Ideally above will help in transfer traffic from br-int to br-ex via path ( as we have physical interface tagged in br-ex ). Is this expected behaviour ? Can some one please help on this ?
