A computer that is running Windows Server 2008, Windows Vista, Windows 7 or Windows Server 2008 R2 sends Internet Group Management Protocol (IGMP) v1 membership report packets to the incorrect destinations. Therefore, applications or services that use the Internet Group Management Protocol (IGMP) v1 protocol are dropped by the router from the multicast group and do not receive any more traffic.
In a captured network trace, the destination IPv4 address differs from the multicast address in the IGMP v1 membership report. Therefore, the design does not comply with Request for Comments (RFC) 1112.
For example, the following resembles a captured network trace that is generated when this issue occurs.
In a captured network trace, the destination IPv4 address differs from the multicast address in the IGMP v1 membership report. Therefore, the design does not comply with Request for Comments (RFC) 1112.
For example, the following resembles a captured network trace that is generated when this issue occurs.
Frame: Number = 33, Captured Frame Length = 46, MediaType = ETHERNET
+ Ethernet: Etype = Internet IP (IPv4),DestinationAddress:[MAC address],SourceAddress:[MAC address]
+ Ipv4: Src = IP address, Dest = IP address, Next Protocol = IGMP, Packet ID = 5009, Total IP Length = 32
- Igmp: IGMPv1 membership report
Type: IGMPv1 membership report, 18(0x12)
- Igmpv1:
Unused: 0 (0x0)
CheckSum: 13509 (0x34C5)
