classless routes

[Enrique de Guindos Carretero]

Hello.
I'm new to dhcp and I'm having a problem.

I have read RFC 3442 concerning classless routes sent to the dhcp clients.

As I saw, Windows clients are using code 249 while the standard one is 121.
On Windows clients I have no problems. But I have troubles on Linux ones.

On my dhcpd.conf I have:

option  ca-static-routes code 121 = string;
option  ca-static-routes 18:C0:A8:00:C0:A8:00:01;

In order of having  192.168.0.0/24 routed through 192.168.0.1 router.
Changing the code with 249 works for windows clients. But with code 121, my
Linux clients are receiving nothing and they have not the static route
configured.

Is it there any solution?

Thx, in advance,

E. Guindos
