OK - I did change the raddr to 0.0.0.0/0 too (and delete the proxy ID on
the juniper).

Ping from OS to 192.168.100.1 (i.e. the IP of the Junipers tunnel
interface) still works.

Now the tunnel get's established and I see multicasts flying all over
the place (i.e bidirectional).

Juniper show Opensolaris as neighbor in state exchange. Better, but not
quite, what I need.

Here's, what I captured on the tunnel-interface of the Juniper:

Quagga isn't too thrilled either:

kunde003-wan# sho ip ospf neighbor

    Neighbor ID Pri State           Dead Time Address         Interface
RXmtL RqstL DBsmL
192.168.100.1   128 ExStart/DROther   31.773s 192.168.100.1
ip.tun0:192.168.100.2     0     0     0

I spotted that the Juniper sends a /32 Mask (since it's
Tunnel-Interface-IP is /32), but quagga sends a /0 mask, although
ip.tun0 has /32 configured.

Is that, why they don't transit into full neighborhood? 

What needs to be changed to get them to agree?

Cheers,
Kai
