dhcp server + router information

In spite of having routers lines in dhcpd.conf

host sidux {
hardware ethernet 00:00:39:34:52:84;
fixed-address 192.168.3.23;
option domain-name "home.network";
option subnet-mask 255.255.255.255;
option broadcast-address 192.168.3.255;
option routers 192.168.3.152;
option domain-name-servers 192.168.2.1;
}

my laptop running sid does not pick up any route when
it boots. It gets the address, and the nameserver, but
running /sbin/route shows the routing information is empty.

I can run a script to add the local wired route, and the router
as the gateway, but the router info used to be passed by the version
2 dhcp server I used to have. The version installed is 3.

When I run wireshark, it shows some IGMP and MDNS traffic (actually a lot
of it on ipv6) where the laptop is looking for routing information.

avahi-daemon is running locally on the server, but according to netstat it
is only listening to sockets down in /var/run.

Could it be that the dhcp server is not providing the router to the client because
it expects avahi-daemon to hand it out? Then it would fail because avahi-daemon is
not listening to the network.
