DLNA and Cisco Routers

[Michael Durham]

Has anyone been able to get DLNa to work over different subnets using Cisco 3550 router/switches? 

My home network has several subnets and I am not going to flatten my network.  What I would like to do is have my media server (a HP Prolian DL380 running VM Ware and Windows) that is on 192.168.125.0/29 netowrk be seen and usable on my users network which is 192.168.69.0/24 and on the wireless lan which os 192.168.200.0/24. 

There are several other netowrks but they do not need access to the media content.

Does anyone know how to do this?

I guess DLNA uses UPnP which uses SSDP which uses 239.255.255.250 multicast group. Probably you need to set up multicast routing:

I would choose PIM dense mode.

Home networking is becoming quite challenging these days (-:

I have been working with thah document but since I am just a CCNA with only home lab experence, I am still a little lost.  In other words, it still not working.  Here is my sh run:

!

ip multicast-routing

!

interface Vlan69

description - User Vlan

ip address 192.168.69.1 255.255.255.0

ip helper-address 172.16.2.2

ip pim version 1

ip pim sparse-dense-mode

no ip route-cache cef

no ip route-cache

!

interface Vlan125

description - Media Vlan

ip address 192.168.125.1 255.255.255.248

ip pim version 1

ip pim sparse-dense-mode

no ip route-cache cef

no ip route-cache

!

ip pim send-rp-announce Vlan125 scope 5

ip pim send-rp-announce Vlan69 scope 5

ip pim send-rp-discovery scope 5

!

Right now I am not worried about restricting anythin.

On my server which is 192.168.125.4/29 I am running PlayOn Media server.  If I am right, once working I should see that server in my Windows 7 workstation which is on ip 192.168.69.150.

I think I am close but no cigar yet.  Any thoughts?

[Michael Durham]

This is my home netowrk.  On the left is my 192.168.69.150 workstation and on the right is the PlayOn Media Server 192.168.125.4.  As you se, I have two 3550-PWR-24 swtiches.  The above config file is from the one on the right.  Do I need to do anything to the switch on the left?

[Peter Koltl]

Use PIM version 2.

It would be easier to set up a static RP.

Enable IGMP snooping on all switches

Check the status while DLNA is supposed to perform some operation:

sh ip mroute

sh ip igmp groups

sh ip pim rp

You need to check whether there is a sender and a receiver in that multicast group.

For some reason, my switch only suppoets version 1.  UGGGG!!!!!

C3550 Software (C3550-IPSERVICES-M), Version 12.2(44)SE6, RELEASE SOFTWARE (fc1)

I still need help with this.  Anyone have any suggestions?  My switch only supports PIM ver 1

[Peter Koltl]

I think it does support PIMv2.

Configuring Basic Multicast Routing

ip pim version [1 | 2]

Configure the PIM version on the interface. By default, Version 2 is enabled and is the recommended setting.

What is your output? Just remove this line if you can't set v2.

Anyway, you can set the other features I suggested (static RP or dense mode and IGMP snooping).

Use the show commands and copy here what you achieved.

[Peter Koltl]

any outcome?

[Mark Simpson]

Well, it may be an old thread, but it was most helpful.

I added the ip pim send's and discovery and the PIM settings on the vlan interfaces for my server and AV VLANs.

Works perfectly.

I have Bose Sound Touch to play the audio and my music library runs on a Synology NAS.

Love it when a plan comes together. 

Thank you Michael.

Mark.

[Peter Koltl]

Glad to hear that. (-:
