hello all,

that's my problem,

+

i have a LAN, witch 4507, and 18 cisco 2960, all running in basic ios image((cat4500e-IPBASE-M), Version 12.2(50)SG3) ((C2960-LANBASEK9-M), Version 12.2(44)SE6 ), all acces switch are connected with the Giga 0/1 port to the core switch with Fiber.

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
