Hello All.
Multicast video streaming is not working for only one VLAN (172.28.7.0/24)
How to find The router is detecting IGMP hosts to join group ?
Pls guide me to make this works.
Please find below few outputs from Router:
ip multicast-routing
interface GigabitEthernet1/0.3
ip address 172.28.7.254 255.255.255.0
ip pim sparse-dense-mode
ip igmp query-interval 125
end
sh ip igmp interface
GigabitEthernet1/0.3 is up, line protocol is up
Internet address is 172.28.7.254/24
IGMP is enabled on interface
Current IGMP host version is 2
Current IGMP router version is 2

Hi,
If it is only for one vlan and multicast does not need to be routed you don't need ip pim sparse-dense-mode
Can you add
ip igmp snooping querier
and test again

Hi,
From the IGMP group output, you have 172.28.7.114 as a host. Is that the host not receiving mcast stream? What switch is connecting to the router? Is it doing IGMP snooping?
