Hi Community, I would like to create a backup of my interface using OpenvSwitch and Flow Rules. I have two VXLAN Tunnel and I want that one of them would be the backup of the other one. I have seen that OpenvSwitch could use two possibilities to make that: group using the fast-failover and bounding using as a backup one of the interfaces. However, I don't see that any of the possibilities could work with a VXLAN/GRE Tunnel only works with normal ports, which are connected to the bridge. For example, I can see that using the command ovs-ofctl mod-port <bridge> <iface> down the difference between the two ports are shown below: user@openvswitch:~$ sudo ovs-ofctl mod-port br-1 ens5 down user@openvswitch:~$ sudo ovs-ofctl mod-port br-1 vxlan1 down user@openvswitch:~$ sudo ovs-ofctl show br-1 OFPT_FEATURES_REPLY (xid=0x2): dpid:0000005000000102 n_tables:254, n_buffers:256 capabilities: FLOW_STATS TABLE_STATS PORT_STATS QUEUE_STATS ARP_MATCH_IP 1(ens5): addr:00:50:00:00:01:02 config: PORT_DOWN state: LINK_DOWN speed: 0 Mbps now, 0 Mbps max 2(ens6): addr:00:50:00:00:01:03 config: 0 state: 0 speed: 0 Mbps now, 0 Mbps max 3(vxlan1): addr:da:8a:d5:81:7f:c1 config: 0 state: 0 speed: 0 Mbps now, 0 Mbps max 4(vxlan2): addr:2a:ef:30:0c:e1:7f config: 0 state: 0 speed: 0 Mbps now, 0 Mbps max LOCAL(br-1): addr:00:50:00:00:01:02 config: PORT_DOWN state: LINK_DOWN speed: 0 Mbps now, 0 Mbps max OFPT_GET_CONFIG_REPLY (xid=0x4): frags=normal miss_send_len=0 As you can see, the vxlan1 was not down. The problem is that the fast-failover uses both flags to determine which port is "live". Is there really any way to know when a VXLAN port is down? If I know when a VXLAN port is down for any reason, I could use Flow Rules to change the priority and use the backup. Thanks for any help that you could give me
