Hi,
I've configured our network for multicast routing but on one of our building network ( L3 with 3750 and access layer with 2950 switches), the multicast traffic is intermittently not forwarded between 2 vlans.
The senders are located in a vlan 192, the receiver is located on a vlan 249. Both vlans are routed on the same 3750.
The IGMP group registration seems to work fine. The multicast mroute table looks good but sometimes, the receiver does not see the multicast traffic arriving on the port. It's intermittent. Sometimes, it receive the multicast traffic sometimes not. ( the traffic concern video camera over IP)
Could you please help me to solve the issue ?
Network config is the following
Distribution layer - two 3750 with 2 vlans 192 and 249 (in HSRP)
Access layer - 2950 switches
