ipv6 multicast subscription canceling problem
![[fi]](/s/countries/fi.gif) Shadow Hawkins on Monday, 02 February 2004 15:58:16
I have got sixxs ipv6 multicast radio working with freeamp-v6, but it seems that multicast subscription isn't canceled after I close freeamp. I compiled ecmh with debug it shows following:

So is it freeamp-v6 fault that subscription isn't canceled or ecmh ?

ecmh... as mentioned on the ecmh page.

Where is that mentioned or am I blind? And is there any way to get rid of that multicast traffic. I'm now receiving > 128kbps unnecessary multicast traffic.

The item "Timing issues" mentions it very briefly. The POPs of SixXS have been running the fixed code for over a week now thus those will unsubscribe after the timeout (5 minutes) is reached and no new subscriptions are sent.

Quite strange that I'm receiving multicast traffic after 8h of last subscription. Last time it took also many hours that multicast traffic stops.

Now after 2 days when I shutdown ecmh, I still get multicast traffic on tunnel T864.

Are you sure that your host is not sending replies back requesting a subscription?
