--- Comment #2 from Tomas Hozza <thozza redhat com> ---
This is *NOT A BUG* in dnsmasq-2.48.

If you read dnsmasq manual page, you will realise, that there is no such way to
set TAGs by using "set:tag0" and also to refer to a TAG by "tag:tag0".
Therefore it is not working with your options.

There was a change in dnsmasq-2.53 which introduced the *NEW* TAGs setting and
referring, but these options are *NOT AVAILABLE* in dnsmasq versions lower than
2.53.

Regarding to dnsmasq-2.48 manual page, you can use existing options to SET the
TAG and to refer to a TAG. In your case if you use:

--dhcp-range=tag0,192.168.253.0,static,120s
instead of
--dhcp-range=set:tag0,192.168.253.0,static,120s

and in the dhcp-optsfile:

tag0,option:dns-server,10.254.254.42
tag0,option:router,192.168.253.1

instead of

tag:tag0,option:dns-server,10.254.254.42
tag:tag0,option:router,192.168.253.1

everything will work. I tested it and server returned right options in DHCP
reply.

Changing Product to Red Hat OpenStack and component to openstack-quantum, since
this is *NOT* a dnsmasq bug.

OpenStack need to be fixed to use proper options when running dnsmasq!
