INTER VLAN & MULTICAST ?

Hello,

I know that the reason for making VLAN's is to create different networks and BROADCAST DOMAINS but .....

At one of our customers some IT guy has put everithing that go over wire CAT 5 cable on VLAN 1 and everithing on Wireless is on VLAN 10.

LAN = VLAN1 = 192.168.1.x/24

WLAN = VLAN10 = 192.168.10.x/24

I can ping from and to both networks , but our customer would like to be able to stream some music from his handheld device (DLNA or AirPlay)  to a device that is connected by cable.

I do not think this will be possible.

Sorry for asking this maybe stupid question but I do not have my CCNA yet , I am still learning

If their any way to create some ACCESS-LIST that will make a MULTICAST possible over both networks ?

At the moment the only thing that the IT guy told me was that he has only 2 ACCESS-LIST :

interface FastEthernet0/1.1

encapsulation dot1Q 1 native

ip address 192.168.1.1 255.255.255.0

ip nat inside

ip virtual-reassembly

no cdp enable

!        

interface FastEthernet0/1.10

encapsulation dot1Q 10

ip address 192.168.10.1 255.255.255.0

ip nat inside

ip virtual-reassembly

no cdp enable

ip nat inside source list 101 interface FastEthernet0/0 overload

ip nat inside source list 110 interface FastEthernet0/0 overload

access-list 101 permit ip 192.168.1.0 0.0.0.255 any

access-list 110 permit ip 192.168.10.0 0.0.0.255 any

PS: Just to prove that our streaming SW was working I have put a simple AP point on one of the CAT 5 cables and everithing work fine , but I can not leave this like that.

Any Help is welcome

Thank You in advance.

Best Regards,

Didier

Airplay uses mdns for communication which uses 239.0.0.251 for an address. 239.0.0.251 is a local multicast address and will not leave the subnet/vlan due to its scope. The only way that you'll be able to get Airplay to work is when it's on the same subnet as the device that needs to access it. As far as dlna, I don't have any experience with these appliances/devices, so you *might* be able to get them to work across the subnet, but from what I've read they support UPnP which enterprise Cisco devices do not support.

Hello,

Maybe some others have the same question.

I just found a really well made document from CISCO , that explain what to do.

It is in PDF found via GOOGLE so I have attached the link to this post : http://www.google.be/url?sa=t&rct=j&q=airplay%20over%202%20vlan&source=web&cd=5&ved=0CEEQFjAE&url=http%3A%2F%2Flistserv.educause.edu%2Fcgi-bin%2Fwa.exe%3FA3%3Dind1202%26L%3DWIRELESS-LAN%26E%3Dbase64%26P%3D1954676%26B%3D--%253D__Part0C2208FA.0__%253D%...
