Hi Dear, I setup my LVS/NAT system by keepalived and it works. I configured the persistent timout as 360 seconds I have one question when enable IPVS connection synchronization, I found the expiration time of persistent template in Backup director is updated to original value as long as packets are coming in Master Lunix director
Please see following example: 1. On Master: [root@0210-lvs-master ~]# ipvsadm -Lcn IPVS connection entries pro expire state source virtual destination UDP 04:54 UDP 10.195.52.11:5060 10.195.52.18:5060 192.168.0.4:5060 UDP 05:53 UDP 10.195.52.11:0 10.195.52.18:5060 192.168.0.4:5060 On backup: [root@lvs-backup ~]# ipvsadm -Lcn IPVS connection entries pro expire state source virtual destination UDP 04:49 UDP 10.195.52.11:5060 10.195.52.18:5060 192.168.0.4:5060 UDP 05:50 UDP 10.195.52.11:0 10.195.52.18:5060 192.168.0.4:5060 2. Send the traffic 3. On Master [root@0210-lvs-master ~]# ipvsadm -Lcn IPVS connection entries pro expire state source virtual destination UDP 05:00 UDP 10.195.52.11:5060 10.195.52.18:5060 192.168.0.4:5060 UDP 05:12 UDP 10.195.52.11:0 10.195.52.18:5060 192.168.0.4:5060 On Backup [root@lvs-backup ~]# ipvsadm -Lcn IPVS connection entries pro expire state source virtual destination UDP 04:18 UDP 10.195.52.11:5060 10.195.52.18:5060 192.168.0.4:5060 UDP 06:00 UDP 10.195.52.11:0 10.195.52.18:5060 192.168.0.4:5060 You can see the expiration time of persistent template on backup director is updated to 6 min, and the expiration time won't also be synced, why the persistent timeout on backup is updated each time? Is it by design? Anyone can help to answer the question? Thanks in advance.
