Is there anybody experiencing the same?
The option static-routes ....... doesn't propagate the static routes to
the dhcp clients. Maybe I'm doing something wrong....

Can you share an example of what you are doing, perhaps someone can give it a
sanity check for you. Don't share any settings you don't want someone outside
your organization to know, of course - find-replace with something irrelevant
to your network as necessary.
Off-hand, I don't know if I still have any active static-routes in my
configuration, but there are much more experienced folks that see these
messages than I and one of them might be able to see if there is an error in
what you are attempting.
I guess another good question is: Did it work before? If so, has anything
changed?
Patrick

The first thing to remember is that the server will (with only a couple of
exceptions) only send options the client asks for, so check if the client is
asking for it. Network sniffers like Wireshark are useful for this.
It?s possible to force the server to send an option the client didn?t ask for,
but ...
If the client isn?t expecting and option, or doesn?t know how to handle it,
then it?s unlikely to have any effect.
I have a rather vague recollection of discussions around this option here in
the past - and vaguely recall that most clients neither request it, nor know
what to do with it if it?s sent.
So :
Does the client ask for the option ?
If it does, is it being sent by the server ?
If it?s being given the option, does the client actually know what to do with
it ?
