The server doesn't push these down for you?

Yes, server does. And I have specific options in dhclient.conf for them:

option rfc3442-classless-static-routes code 121 = array of unsigned integer 8;

interface "eth0" {
request subnet-mask, broadcast-address, routers, ntp-servers,
        domain-name, domain-name-servers, host-name,
        netbios-name-servers, netbios-scope, interface-mtu,
        rfc3442-classless-static-routes;
}

But how I can get that option value from dispatcher script?
It was easy to get the option from dhclient-exit-hooks, because it runs from dhclient enviroment where necessary variables are set.

If not, you can also add routes through the NM connection configuration
too.  See the connection editor, IP4 tab, Routes... button.

Not the solution, because I have to get routes from dhcp. They can change.
