Hello! I use a router TP-LINK R480T +. I have 2 servers on which is Linux - "CentOS 5.6" I use failover with UCARP. "UCARP allows a couple of hosts to share common virtual IP addresses in order to provide automatic failover ". The router gives the IP address of 192.168.1.5 (00:00: E8: 05:17:25) to a single server, and 192.168.1.6 (00:0 D: 61:70: F0: A6) the second server. On the first server (192.168.1.5 - 00:00: E8: 05:17:25) rises with the alias IP address of 192.168.1.10. Port Forwarding -> Virtual server on the router is configured with the IP address 192.168.1.10 With the fall of the first server, alias 192.168.1.10 rises on the second server (192.168.1.6 - 00:0 D: 61:70: F0: A6) But the router still has about 5 minutes, continues to send packets to the first server with MAC adress 00:00: E8: 05:17:25
