Configuring Cisco Switch VLANs for Samsung DLNA Sharing!

[Abdullah Net]

Hello there,

In my vlan 40, I have Samsung Smart TV and Samsung Allshare "DLNA" software on one of my PCs in the same vlan. Everything works fine and I can watch movies on my TV streaming from my PC.

Now, my brother, which is in Vlan 20, bought Samsung Smart TV.

I want my PC, which hosts Samsung Allshare software (vlan40), to send its media streaming to my brother's TV (vlan20) so he can watch my movies.

I know broadcasts are dropped between vlans.

So, How can I accomplish that?

Hi,

Have a look at this link:-
http://www.cisco.com/c/en/us/support/docs/ip/ip-multicast/9356-48.html

If your switch is doing the inter vlan routing (IE Layer3 compatable)

Then a simple DENSE mode config something like this should be OK.

!
ip routing
ip multicast-routing dist
!
int vlan 20
desc ***MY BROTHERS VLAN ***
ip add 192.168.20.1 255.255.255.0
ip pim sparse-dense-mode
no shut
!
!
int vlan 40
desc ***MY  VLAN ***
ip add 192.168.40.1 255.255.255.0
ip pim sparse-dense-mode
no shut
!

Alex,

"ip multicast-routing dist" doesn't exist in my switch. I can only see "ip multicast-routing" which i used along with the rest of your suggested configurations but with no luck.

Alex,

I got "ip multicast-routing dist" to work by upgrading the IOS.

And your method worked :)

Quick question!

In which Cisco certification exam/course IP multicasting is covered?

Abdullah,

Never saw anything to involved with multicasting in CCNA or CCNP at all.

Just picked up bits and pieces myself through the years.

This link is quite descritive

http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipmulti_pim/configuration/12-4t/imc-pim-12-4t-book.html

Just google & CCO config guides etc

Hope this helps
