Multicast Routing on 5406R zl v2

Hi all, 

I'm hoping someone here can assist. I have a 5406R zl v2 switch that I am intending to use as my new core switch in preparation for an IPTV implementation we're planning to do.

I have a VLAN, 104, that will have the IPTV headend in it, and it will be the source of the UDP streams for each channel. 

I am trying to get a machine in VLAN 108 to connect to one of the multicast groups in VLAN 104 with no success.

Here's how I've got things set up in my lab environment:

Source PC
VLAN: 104
Port: A1
Unicast IP: 10.0.4.200
GW: 10.0.4.254
UDP streaming via VLC on udp://@239.1.1.1:1234

Destination PC
VLAN: 108
Port: B1
Unicast IP: 10.0.8.201
GW: 10.0.9.254 (it's a /23)

I can ping each machine's unicast IP from either end, so L3 routing is working fine. It's just using the connected VLANs on the switch, so there are no routing protocols defined. If I put both machines in the same VLAN (104), it works no problem.

I have set up PIM-SM as well as I could based on the HPE Multicast documentation. When I do 'sh ip mroute' it's blank, so I'm guessing something isn't correct there. There are no errors in the log as such, so I'm not quite sure what piece of the puzzle is missing.

On a number of threads it was suggessted to reboot the switch after enabling 'ip multicast-routing' and the PIM-SM routing which I have done to no avail.

Here's the config I've got:

Re: Multicast Routing on 5406R zl v2

So I managed to figure out what the issue was and thought I had better fill you in.

It turned out to be the TTL value set by VLC when you start a UDP stream. By default the TTL is 1, so after one hop, the packets die (explains why it worked on the same VLAN). If you set it to something like 15 in the command line edit screen before kicking off the stream, it'll work a lot better :)

So on this occasion, the network config was correct. It was an application issue.

Cheers,

Lachlan.
