Why doesn't route work in dhcpd?

Question

Network routing

Hello!
I have DHCPd, the routers option is set in it and there are several IPs (6) in the parameters. The problem is that the client on CentOS 7 does not route when the 2nd (10.1.2.10) server in the list from routers is present on the network.

subnet 10.1.0.0 netmask 255.255.252.0 {
...
        option routers                  10.1.3.254, 10.1.2.10, 10.1.2.254, 10.1.1.254, 10.1.0.254, 10.1.0.1;
}

The router naturally sees the network. If you specify only one router IP in option routers, everything works fine. In theory, the client should ask 10.1.3.254, if he does not answer, then further 10.1.2.10, etc.
This is my mistake somewhere (or I don’t understand) and what is the reason?

From documentation:

option routers ip-address [, ip-address...];
List of router IP addresses for the client network. Routers should be listed in order of preference.

Those. you only need to specify the gateway address for each subnet. You have two addresses on 10.1.2.0 and 10.1.0.0 subnets.
