All things related to multicast

[Tim Chown <>]

Hi Marc,

The looking glass you are using is hosted here with us.  What exactly 
do you want to do?    

If I use the lg to do an ipv6 ping to mini.stattfernsehen.com I see:

/bin/ping6 -c 10 mini.stattfernsehen.com
PING mini.stattfernsehen.com(mini.stattfernsehen.com) 56 data bytes
64 bytes from mini.stattfernsehen.com: icmp_seq=0 ttl=46 time=64.5 ms
64 bytes from mini.stattfernsehen.com: icmp_seq=1 ttl=46 time=63.6 ms
64 bytes from mini.stattfernsehen.com: icmp_seq=2 ttl=46 time=64.4 ms
64 bytes from mini.stattfernsehen.com: icmp_seq=3 ttl=46 time=63.7 ms
64 bytes from mini.stattfernsehen.com: icmp_seq=4 ttl=46 time=63.1 ms
64 bytes from mini.stattfernsehen.com: icmp_seq=5 ttl=46 time=63.9 ms
64 bytes from mini.stattfernsehen.com: icmp_seq=6 ttl=46 time=63.5 ms
64 bytes from mini.stattfernsehen.com: icmp_seq=7 ttl=46 time=67.6 ms
64 bytes from mini.stattfernsehen.com: icmp_seq=8 ttl=46 time=64.4 ms
64 bytes from mini.stattfernsehen.com: icmp_seq=9 ttl=46 time=65.0 ms

--- mini.stattfernsehen.com ping statistics ---
10 packets transmitted, 10 received, 0% packet loss, time 9009ms
rtt min/avg/max/mdev = 63.151/64.418/67.686/1.239 ms, pipe 2

This suggests that IPv6 unicast connectivity from the lg server to
mini.stattfernsehen.com is fine.

However, we do have some IPv6 multicast connectivity issues on the lg
server since Christmas, which we believe are related to some firewall
changes made.   This is under investigation.

Note anyone is free to download and run the lg on their systems; the
more that are available the better :)
