Network Management

I am working on setting up a scenario to work on learning and playing around with Multicasting. I have a network of 3 switches and 2 laptops to sandbox this out. I believe that I have it setup right but when I try to use this multicast testing tool Software Download: IC_Tester_Multicast.zip it does not work. Here is what I have setup.

6405 - Core
vlan 50
MCast testing
ip igmp snooping enable

interface 1/4/31-1/4/32
MCast Testing
vlan access 50

interface vlan 50
MCast vlan
ip address 10.80.50.1/29
ip ospf 5 area 0
ip ospf cost 1
ip igmp enable

router ospf 5
RID 10.80.5.0
area 0

6300-Top
vlan 50
Mcast test
ip igmp snooping enable

interface 1/1/10
Mcast device
vlan access 50

interface 1/1/30
Mcast test to 6300-Bot 1/1/30
vlan access 50

interface 1/1/31
Mcast test to Core 1/4/31
vlan access 50

interface vlan 50
MCast test vlan
ip address 10.80.50.2/29
ip ospf 5 area 0

router ospf 5
rid 10.80.5.1
area 0

6300-Bot
vlan 50
MCast test vlan
ip igmp snooping enable

interface 1/1/10
Mcast Device
vlan access 50

interface 1/1/30
Mcast test to 6300-Top 1/1/30
vlan access 50

interface 1/1/32
MCast test to Core 1/4/32
vlan access 50

interface vlan 50
MCast test vlan
ip address 10.80.50.3/29
ip ospf 5 area 0

router ospf 5
rid 10.80.5.2
area 0

2 test laptops have ip address of 10.80.50.5 and 10.80.50.6

I can ping between the devices so I know the devices can communicate. They were able to communicate before adding OSPF. I recently added the OSPF to see if that would allow the multicast which it did not.

I have tried adding the 239.0.1.2 group which is the default for the tester and still was not able to get the multicast to work. I have not setup PIM or DIM. Is that required for simple Multicasting?

Is there something wrong with my config?

I believe multicast packets do require some kind of routing protocol running, such as PIM, to route those packets between your switches and VLANs. So while you have routing protocols such as OSPF running for unicast traffic, you need PIM set up to deal with multicast traffic. 

We have PIM sparse mode running. I don't believe dense mode was added into the CX operating system until a much later software release.

IGMP will help prune your traffic down to only those devices that care to hear the multicast traffic. Just double check you are enabling igmp anywhere the vlan exists, including other switches

I'm glad I found this post; I am also in the process of getting ready to deploy a whole new 6300 switch network that will require some multicast settings throughout my entire network, and this is the kind of information I was looking for, by no means an expert on Aruba switches. Where can I go to get up to speed on this MCast settings for my new switches?

I have not enabled PIM yet which I will try. While reading this document, I was thinking that I need to enable IGMP on L3 interfaces and IGMP Snooping on L2 interfaces. I was working on it last night and will finish and do some testing today.

AOS-CX 10.10 Multicast Guide for 6200, 6300, 6400, 8320, 8325, 8360, 8400, 10000 Switch Series

I guess my question at this point is can I keep all the ports in the same vlan or do I need to do different vlans and keep the vlan for the devices as L2 not L3?
