Add static route to one specific address to dhcpd.conf

I want to add a static route to 10.13.0.1/32 via 192.168.178.10 to my dhcpd.conf of my dhcpd server. Unfortunately this seems to be insanely complicated. I tried the following: option static-routes 10.13.0.1 192.168.178.10; However this will add a route to 10.0.0.0/8 via 192.168.178.10 which is undesired. I also tried: option rfc3442-classless-static-routes code 121 = array of unsigned integer 8; option ms-classless-static-routes 32, 10, 13, 0, 1, 192, 168, 178, 10; Which results in the dhcpd to no longer start: Feb 13 20:49:30 csh-gw dhcpd: For info, please visit https://www.isc.org/software/dhcp/ Feb 13 20:49:30 csh-gw dhcpd: /var/lib/dhcp//etc/dhcpd.conf line 63: unknown option dhcp.ms-classless-static-routes Feb 13 20:49:30 csh-gw dhcpd: option ms-classless-static-routes 32, Feb 13 20:49:30 csh-gw dhcpd: ^ Feb 13 20:49:30 csh-gw dhcpd: Starting ISC DHCPv4 Server Feb 13 20:49:30 csh-gw dhcpd: please see /var/log/rc.dhcpd.log for details ..failed Googling for this issue did only yield results of adding routes to entire networks including a default gateway, which I do not want.
