multicast server into existing vlan network
Posted on 2011-05-03
We have a network setup with 3 vlan's, one for guest access, one for corporate and one for a shared internet access.
We now need to install the multicase application i.e. one sender with multiple recievers, and my initial plan was to create another VLAN for this to seperate the traffic from the other VLAN's. Now i don't know much about multicase other than the concept i.e. you subscribe to a broadcast rather than the server sending multi requests to it's subscribers, it sends one broadcast and you subscrib to see the broadcast to see the video.
I'm just tryting to get a head start before they turn up to install the application.
Now can i put the multicast class D into a VLAN and do i need too.
The provider has said i should try to use a address range from 220.127.116.11 to 18.104.22.168. Now i don't fully understand the class D address, do they have subnet masks. For instance if i wanted to define a VLAN for 22.214.171.124 for 254 hosts i thought the subnet would be the same as a class C address but our layer 3 netgear switch (GSM7328) complains that the address is not in the same subnet as the gateway.
I also seen i should enable IGMP snooping on our layer 2 switches, and also configure a IGMP query device on our core layer 3 switch, any advice welcome on this as well.
Thanks in advance
