Hi community, I'm trying to achieve the following. Could anybody tell me what has to be configured on the router running IOS 15.5?
1. Interface Vlan72 receives IGMP Membership Report from end hosts in the segment.
2. The router populates its MRIB with a corresponding (*,G) entry.
3. A new IGMP Membership Report is generated by the process and is sent via interface Gig8 to the Service Provider.
4. Service Provider gets the IGMP Membership Report and starts sending the feed.
5. Our router receives feed and forwards it out the interface Vlan72, where receivers are.
The problem is that we do not run PIM with the Service Provider, so our end (CPE) has to act as a plain receiver sending IGMP Report messages over the link. By not running PIM, I mean we do not receive any PIM Hello over the link.
They said we should enable IGMP Proxy to achieve our goal, but the only information I could find is related to Unidirectional-Link environment and I couldn't find out how to apply it to my situation.
I already verified that we actually receive multicast packets by setting ip igmp join-group 220.127.116.11 on Gig8, which is why I believe that if we could somehow «proxy» the Membership Reports to the SP, that'll solve the problem.

When moving from OSPFv2 to OSPFv3, there are many changes in the format of the LSAs Type, but the most known changes are: IP prefix informations are no longer carried in Type-1 LSA and Type-2 LSA, new LSAs Type 8 and 9 are added to carry these prefixes.
