This may be a stupid question, but do the two servers need to have
the same peer name? Mine have two different names, and this works,
though I really do not understand which name is to go with which
server...
The host name of my primary ist DHCP-0465, and I put DHCP-0465 in its
peer declaration; the secondary's host name is DHCP-0352, and I put
DHCP-0352 in its peer declaration. Like this:
failover peer "DHCP-0465" {
primary;
address 130.60.23.4;
port 520;
peer address 130.60.23.114;
peer port 520;
max-response-delay 60;
max-unacked-updates 10;
mclt 3600;
split 128;
load balance max seconds 5;
}
and:
failover peer "DHCP-0352" {
secondary;
address 130.60.23.114;
port 520;
peer address 130.60.23.4;
peer port 520;
max-response-delay 60;
max-unacked-updates 10;
load balance max seconds 5;
}
Is that wrong???
