I have a need to selectively block traffic to a multicast group which may have
multiple
subscribers on the same host. I'd like to use IP Filter to block the multicast
traffic to
certain subscribers in the multicast group, but not others. Subscribers are in
separate
non-global zones on the same host.
Here is an example scenario:
* One process running on host foo multicasting to 225.4.5.6 group
non-global zone bound to IP X
* Two processes running on host bar subscribed to 225.4.5.6 multicast group
non-global zone bound to IP Y
non-global zone bound to IP Z
Can I create a rule that blocks multicast packets sent by X from getting to Y
but allows
them to pass to Z?
OS is Solaris 10 Update 4. All processes are running on separate non-global
zones. For
technical reasons stemming from our use of VLANs, we can't make use of
exclusive IP zones
and filtering is done in the global zone.
Can the (undocumented) multicast option type help here? My feeling is no, but...
Thanks
- Andres
