The range of addresses between 224.0.0.0 and 224.0.0.255 inclusive, is
reserved for the use of routing protocols and other low-level topology
discovery or maintenance protocols, such as gateway discovery and
group membership reporting. Multicast routers should not forward any

Hi Philip
So with a bit of poking and prodding, we have a much better
understanding as to why this is O.K. Maybe your next patch can quote
the relevant RFCs and have a much fuller commit message?

IGMP reports are generated for link local multicast groups (224.0.0.1
- 224.0.0.255) used by the routing protocols such as RIP, OSPF etc.
In general routers do not generate reports for local multicast groups.
IGMP reports for local multicast groups can now be inhibited by means
