[lots of mistakes in failover configuration]
What I meant was:
Stage 1:
In /etc/dhcpd.conf on primary-a.test:
failover peer "testa" {
primary;
address primary-a.test;
port 520;
peer address secondary-a.test;
peer port 520;
max-response-delay 60;
max-unacked-updates 10;
mclt 3600;
split 128;
load balance max seconds 3;
}
In /etc/dhcpd.conf on secondary-a.test:
failover peer "testa" {
secondary;
address primary-a.test;
port 520;
peer address secondary-a.test;
peer port 520;
max-response-delay 60;
max-unacked-updates 10;
load balance max seconds 3;
}
Stage 2:
failover peer "testa" {
primary;
address primary-a.test;
port 520;
peer address secondary-b.test; # CHANGED
peer port 520;
max-response-delay 60;
max-unacked-updates 10;
mclt 3600;
split 128;
load balance max seconds 3;
}
In /etc/dhcpd.conf on secondary-b.test:
failover peer "testa" {
secondary;
address primary-a.test;
port 520;
peer address secondary-b.test;
peer port 520;
max-response-delay 60;
max-unacked-updates 10;
load balance max seconds 3;
}
