      Could you please confirm me that the preempt functionality still works on version 2.4.4-RELEASE-p2?
      I've configured two firewalls as master and slave with 2 VIP on both WAN and LAN and a SYNC interface to connect the two. If only one interface fails, CARP will switch only that interface to the slave and not both.
      I the device fails, both interface goes to the slave and switch back as soon as the master is online again.
      I've tried to reconfigure everything twice and also tried with two VMs but with the same result.
      Thank you for your input.

          Netgear SG-3100.
          I don't think it is an hardware problem, I get the exact same results with two virtual machines.

            How are you taking an interface physically down on a VM?

              On the SG-3100 I've tried unplugging the cables or taking the interface down.
              On the VM I've taken the interface down.
              Always the same result, master fails to slave correctly but only for the failed interface and not both (LAN and WAN).
              It doesn't matter which interface I let fail (LAN or WAN), the other never switch together (WAN or respectively LAN)

                What is being logged by the node on which you are unplugging the device?

                It will be in the General system log.

                No, preemption is not broken so we need to figure out why yours is not working. Note that pfSense needs to see actual carrier down. I expect this might be problematic using the SG-3100 LAN switch ports and VM interfaces.

                The logs you are looking for will look similar to this:

                Mar 12 15:53:40 pfSense check_reload_status: Linkup starting igb2
Mar 12 15:53:40 pfSense kernel: igb2: link state changed to DOWN
Mar 12 15:53:41 pfSense check_reload_status: Reloading filter
Mar 12 15:54:10 pfSense kernel: igb3: link state changed to DOWN
Mar 12 15:54:10 pfSense kernel: carp: 13@lagg0: MASTER -> INIT (hardware interface down)
Mar 12 15:54:10 pfSense kernel: carp: demoted by 240 to 240 (interface down)
Mar 12 15:54:10 pfSense kernel: lagg0: link state changed to DOWN
Mar 12 15:54:10 pfSense kernel: carp: 14@lagg1: MASTER -> BACKUP (more frequent advertisement received)

                Note the CARP interface going down demotes the node to advskew 240 which makes the other CARP VIP "slower" than the secondary at 100 so it assumes BACKUP state too. (That is an LACP lagg so it doesn't actually go DOWN until igb2 and igb3 lose link.)

                      You'll have to see if the CARP advertisements are actually arriving on the secondary in that case.

                      Mar 12 17:08:28 kernel arp: 10.0.0.1 moved from 00:00:5e:00:01:02 to 00:08:a2:0e:10:f0 on mvneta1

                      That should never happen. There should never be anything responding to ARP on a CARP VIP with an IS AT anything but the CARP MAC. What is at MAC Address 00:08:a2:0e:10:f0

                          Take a really good look at the configuration of the secondary.

                          Packet capture a bunch of ARP during failover tests and take a good look at that. There should never be an ARP IS AT response for a CARP VIP that contains an interface MAC as the payload. It will be sourced from the interface MAC but contain the CARP Mac. If there is I would like to see the capture.

                              @mylos said in CARP preempt does't work:

                              17:34:48.781554 ARP, Request who-has 10.0.0.1 tell 10.0.0.1, length 28

                              That also makes no sense. Does it make sense to you?

                              Please download and post the raw pcap.

                                  You will need to attach the capture file.

                                  I cannot properly test SG-3100 HA. I only have one unit.
