Hi!

 


source(IPTV) - x480_1 - x480_2 - receiver(VLC)

Everything happens in a single vlan.


x480_1 # sh igmp snooping vlan_777
Router Timeout                :    260 sec
Host Timeout                  :    260 sec
Igmp Snooping Fast Leave Time :   1000 ms
VLAN vlan_777         (777) Snooping=Enabled   
   Group           Sender          Age   
   239.1.1.1       10.50.1.62      25    

                              ..many others channels..
   224.10.1.2      10.50.1.62      4     
                             But where is the request from the receiver? Why doesn't it get to x480_1?

 

x480_2# sh igmp snooping vlan_777
Router Timeout                :    260 sec
Host Timeout                  :    260 sec
Igmp Snooping Fast Leave Time :   1000 ms
VLAN vlan_777         (777) Snooping=Enabled   
   Group           Sender          Age   
   224.0.0.251     10.50.1.66      52    
   239.255.255.250 10.50.1.66      85    
   2 Incoming multicast streams  
   Port   Host            Subscribed        Age    Group-Limit     
   1      10.50.1.66      239.1.1.1         4      0               - 

Multicast streams from the source are not visible and this is ok, igmp snooping is enabled on both switches. Why doesn't the IGMP Membership Report reach the first switch?
