[Xorp-users] Some Questions on XORP

[Archimedes S. Gaviola]

Pavlin,

I have encountered some documents that are useful for multicast source
filtering http://www.ietf.org/rfc/rfc4604.txt?number=4604 and
http://www.ietf.org/rfc/rfc3678.txt?number=3678. I do hope this could help.

Thanks.

Sincerely Yours,

No, currently it can't be done within XORP, but we should add support for
this. I just created a bugzilla entry so you can add yourself to the CC list
and get notified when it is implemented:

http://www.xorp.org/bugzilla/show_bug.cgi?id=695

Currently, the only mechanism that comes to mind is using firewall rules
(outside XORP) to allow (or block) the IGMPv3 Membership Report messages
from a specific set of hosts.

Note that such filtering can be applied only to IGMPv3/MLDv2, because in
IGMPv1,v2 and MLDv1 the hosts use Membership Report suppression.

Regards,
Pavlin
