HI guys,
I have been trying to get IPTV to work with my ISP for some time now and I'm really struggling.
My ISP is BT infinity (FTTC)
I have found these hints on the internet:
- "IGMPv3 is used to control access to multicast.
- Multicast traffic sits in a seperate VLAN to your normal ISP data traffic (i.e not inside the PPPoE session).
- VLAN membership tags are stripped as they leave the Openreach network and are sent to the customer modem.
- IGMP membership requests are rewritten to a source address of 0.0.0.0, and any VLAN tags are stripped as they enter the Openreach network from the customer modem."
This is my core config :
ip multicast-routing

no ipv6 cef

controller VDSL 0
operating mode vdsl2

I can see examples of working config here:

but these people are using ATM where as I am PPOE.
I have tried debugging IGMP but all i get is link local multicast stuff.
