Are you using a production size network here or just a small multicast network to see if things work? It might help others work on some of these issues if we could build a network setup similar to your own, including the tweaks you've made with dladm. The goal here is to be able to build a functional (and small) test case to verify IGMP group membership is working properly so that future changes can be tested for correctness. Just as long as we don't need to be running IPTV :) Cheers, Darren ------------------------------------------- illumos-discuss Archives: https://www.listbox.com/member/archive/182180/=now RSS Feed: https://www.listbox.com/member/archive/rss/182180/21175430-2e6923be Modify Your Subscription: https://www.listbox.com/member/?member_id=21175430&id_secret=21175430-6a77cda4 Powered by Listbox: http://www.listbox.com
