Failover | How sync fixed-addresses definition between master and slave

[Anton Shevtsov]

Hi,

I make failover confuguration, all work fine. But i have one question - 
how sync fixed-addresses definition between master and slave?

My /etc/dhcp/dhcpd.conf from 'primary' node. Static addresses i moved to 
static.conf.

Should I copy manually to 'slave' node (after each change to this file, 
and restart/reload dhcpd service) or are anybody have a best practices?

#primary
authoritative;
update-static-leases on;
one-lease-per-client on;
omapi-port 7911;
omapi-key omapi_key;

failover peer "partner" {
		primary;
		address 172.23.116.20;
		port 519;
		peer address 172.23.116.21;
		peer port 520;
		max-response-delay 60;
		max-unacked-updates 10;
		mclt 3600;
		split 128;
		load balance max seconds 3;
}

key "omapi_key" {
	algorithm hmac-md5;
	secret "--mysecrethere--";
};

subnet 172.23.116.0 netmask 255.255.255.0 {
	option routers			172.23.116.1;
	option subnet-mask		255.255.255.0;
	option nis-domain		"domen.loc";
	option domain-name		"domen.loc";
	option domain-name-servers	172.23.116.20, 172.23.116.21;
	option ntp-servers	172.23.116.20, 172.23.116.21;

	default-lease-time 21600;
	max-lease-time 43200;
	pool {
		failover peer "partner";
		range 172.23.116.30 172.23.116.250;
		include "/etc/dhcp/static.conf";

	}
}

[root at ns1 dhcp]# cat static.conf
host srv1 {
	hardware ethernet 00:50:56:bb:6f:02;
	fixed-address 172.23.116.23;
}

host win10 {
	hardware ethernet 00:50:56:bb:db:87;
	fixed-address 172.23.116.142;
}
