IPTV / IGMP / Multicast / HP 5412zl

[Darren Tickle]

Hey,

Ive been having a good look around these forums at all the multicast questions but cant hit the spot for the problem im having with a new IP TV systems that we are having installed.

I dont have the premium edge lience for our core switch so cant enable ip mulitcast routing. I was woundering if there was another way I could do it? I know the port the traffic runs on, but still waiting to find out if it is TCP or UDP traffic.

We have our Default VLAN with our core switch and other switches in and then 3 other vlans that will want to use the TV service.

1- Default Vlan
2- Staff Vlan
3- Pupil Vlan
4- Server Vlan

The IP TV server is in the Server VLAN and i want to sent the mulitcast traffic to the other VLANS. Off course it works if a client PC is in the same vlan as the server but i cant get it to work cross VLAN.

We are using HP 2610's on the Edge switches as well if that helps.

Below is my core config, ive cropped out some access lists ive done and other vlan infomation to make it abit easier to read.

Hi

Multicast should cross other Vlans....

You need the Premium edge license; and i'm not sure if there a work around for your case to avoid buying the license.

Good Luck !!!

[Matt Hobbs]

If it's UDP you might be able to use the UDP helper feature (most likely it is since multicast is usually one way, in fact is TCP even possible for multicast?). Otherwise you'll need the license.

[Darren Tickle]

Ok I just got back from the IP TV firm that it just sends out UDP packets only.

Can I just use udp forwarding and if any can anyone help me out or point me in the right direction on were to start.

[Jarret Workman]

Hi Darren,

I'm not sure if the UDP forwarding would work or not, but PIM is what allows multicast traffic to cross vlans, which is most likely why you mention not having the Premium Edge License. One of the features that is added with the Premium Edge license is PIM.

It looks like page 5-144 of the Multicast/Routing Guide of the 5400 series begins discussion on UDP forwarding.

Thanks for all the replies, I have ordered the Prem Edge Lience.

I have found the DIM and IGMP manual for the switch, but can anyone explain the config in simple terms for me?

thanks again.

Hi Darren,

4 simple steps:

1- enable ip routing (already done)
2- enable multicast routing (ip multicast-routing)
3- enable PIM router (router pim)
4- enable pim-dense for all required VLAN's
eg.
vlan 100
ip pim-dense
ip-addr any
exit
exit


Good Luck
