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
