This morning when I went to multicast an I2 stream I discovered somehow my multicast is broken to my perimeter router. I can receive SAP announcements, IGMP memberships establish and PIM joins look good. By all accounts it should work.
I spent 14 hours working on this today and am extremely frustrated. I also contacted my local loop provider. Everything seems ok but except for one multicast stream that for some un-explainable reason worksâ¦ no other multicast streaming works. I have tried multiple laptops on the right on the perimeter router, outside all firewalls. Also tried rebooting my router. I spanned my Internet 2 port to another port and put Wireshark on it. The one stream that works shows up plain as day in Wireshark. All the other streams I try don't show up anywhere in Wireshark. Internet 2 sees the traffic increase on their interface to me when I start a stream. My local loop provider also sees the increase in traffic but I don't seem to receive it on my router.
When I compare my router config to my backup from the Presidential Inauguration when I last personally used it...none of the changes made since then affect the I2 connection in any way. Unicast routing works fine. I am completely stumped on this. Has anyone ever seen anything like this on their end? Can someone offer up some advice please.
