i have 18 Vlans, the Vlan 4 is fir the IP camera, and encodeur, the Vlan 6 is for the camera client, our encodeur use multicast to diffude a video to the clients in VLAN 6, and i have a probleme when the encoder when i watch more 6 camera at the same time ( 1 camera use 4 Mb/s ),
i need the configuration to put in the core and acces Switch, to reduce a multicast in my network,
i pute this configuration but its dosnt work:
in the acces switch :
ip igmp snooping vlan 4 mrouter interface Gi0/1
ip igmp snooping vlan 6 mrouter interface Gi0/1
in the core switch :
ip multicast-routing
interface Vlan4
ip address 10.0.4.200 255.255.255.0
ip pim sparse-dense-mode
ip igmp version 3
interface Vlan6
ip address 10.0.6.200 255.255.255.0
ip pim sparse-dense-mode
ip igmp version 3

Hello Hamou,
see if the following command
ip igmp limit is supported on interfaces of your switches
ip igmp limit N
see
http://www.cisco.com/en/US/docs/ios/ipmulti/command/reference/imc_02.html#wp1044048
this could be of help in limiting
or more appropriate
ip igmp max-groups
Hope to help

Hello Hamou,
224.0.1.40 is used by Cisco Auto RP protocol so no worries about this
239.255.255.250 is part of a block that is a sort of private multicast addresses
see
http://www.multicast.org.uk/address-tools/scope-relative.html
this is used by some printers as explained here for SSDP protocol

Hope to help
