IGMP report of MA5616 without valid source-ip address caused Cisco SW can not recognize.

Publication Date:  2012-07-25 Views:  77 Downloads:  0
Issue Description
Version MA5616:
MA5616V800R307C01B051
Topology:
STB ---- modem ----- VDSL board ---- MA5616 (ETH uplink) ====== Cisco SW ------- IPTV sever 
This specific IPTV subscriber is able to be online correctly, whereas there is no related program traffic comes to MA5616 at all. 
Alarm Information
Null
Handling Process
Only there is only one discrepancy between those two captures is Source IP address and Source MAC address, that is to say might it be the factor that cisco SW can not recognize our IGMP report. 
1.Thus far, we are not able to modify source MAC address of IGMP report, however we can make it different at modifying source IP of IGMP report.

{ ip-addr<I><X.X.X.X> }: 169.254.10.143     -----here you can adjust whatever IP address you want. Here I adopt a IP address in capture “in cisco_2.pcap”                                    
                                                                                
  Command:                                                                      
          igmp program modify index 0 hostip  169.254.10.143  
after changing this command, problem solved.
Root Cause
1. Using PC connected with Cisco SW instead of MA5616, it works always. 
2. Making a capture between MA5616 and Cisco SW during this specific IPTV subscriber ordering program
3. Making a capture between this PC and Cisco SW during this PC ordering program.
4. Comparing both capture, we can not find anything difference between both capture except the source-ip of IGMP report. Only it could be a reason, cannot Cisco SW recognize the IGMP report sending by MA5616.
Suggestions
Sometimes, Cisco considers IGMP report message with source-ip address = 0.0.0.0 is illegal, so it will discard it directly.plz see both different captures in the attachment.
