Hi All,
Need a littel help with getting Multicast Video Streaming to work across my Development Network, utilising VLC.
I have a 2811 Router configured with a "NME-16ES-1G-P: EtherSwitch SM 16 10/100T PoE + 1 GE Port adapter, 1 port".
which is the equivalent of a 16 Port 3750 Catalyst POE.
My 2811 is configured with Sub-Interfaces, which is connected to a Trunk port on the 3750 Module.
* The 2811 is configured for Multicast-Routing
* The Sub Interfaces are configured with IP PIM Dense-Mode
* The Sub Interafaces are also configured to Join the Multicast Address 224.1.1.1, 224.1.1.2 & 224.3.3.3
The Issue I have is as follows:
1) If I Ping one of the Multicast Address i.e. 224.1.1.1 from a Host on a switchport connected to either vlans, and display the Mroutes,
the 2811 Router Sub-Interfaces configured with PIM, join the multicast group.
(10.1.1.10, 224.1.1.1), 00:00:06/00:02:59, flags: LT
Incoming interface: FastEthernet0/0.10, RPF nbr 0.0.0.0
Outgoing interface list:
FastEthernet0/0.20, Forward/Dense, 00:00:06/00:00:00
FastEthernet0/0.300, Forward/Dense, 00:00:06/00:00:00
(172.16.1.10, 224.1.1.1), 00:01:39/00:02:29, flags: LT
Incoming interface: FastEthernet0/0.20, RPF nbr 0.0.0.0
Outgoing interface list:
FastEthernet0/0.300, Forward/Dense, 00:01:39/00:00:00
FastEthernet0/0.10, Forward/Dense, 00:01:39/00:00:00
2) However if I apply the same priciple with streaming Video using VLC with the same IP Address, the Sub-interfaces configured with PIM, do not see the traffic. I am of the opinion the 3750 switch ios not broadcasting / Multicasting the Streaming Traffic.
I can pickup the Video stream if I connect a host which is configured in the same Vlan as the Source.
Please note below I have included the configuration of my interfaces.

i.e. Sh IP Mroute the Interfaces configured with PIM joines the group.
Configure Static Mrouter Port on the Switch
Thanks for your Help.
