dhcp failover is not working as expecte

[Julie Xu]

Hi,

I have dhcpd running on two servers. Share the load 50%.

I expect if one of the servers has issue, another one will automatically take over for all 100% clients.

But, the fact is not. When one of them down, or frozen, half of users had lose network without ip address.

My configuration is:
failover peer "primary_secondary" {
    primary;
    address 111.111.111.111;
    peer address 222.222.222.222;
    port 8068;
    peer port 8068;
    max-response-delay 60;
    max-unacked-updates 10;
    mclt 300;
    split 128;
    load balance max seconds 3;
   auto-partner-down 0;
    max-lease-misbalance 15;
    max-lease-ownership 10;
    min-balance 60;
    max-balance 3600;
}

Could I get some explanation on why it is happed? And how to avoid it?

Any comments will be appreciated

Thanks in advance

Julie
