configuration multicast

[nguekotchamande1]

Hello
THAT makes two weeks which I try to configure my router(route planner) Cisco 2800 series to manage a multicast. I would want a precise configuration and complete of this configuration. For example, I have connect my laptop on a port(bearing) of my router(route planner) and on an other port(bearing) the switch where from come the multicast. I would want to read a multicast on my machine since VLC passing by the router(route planner) I wait for your answers. Thank you in advance

Hi,

Consider the bellow topology (GNS):

R1,R2,R3 - 7200.

switch1 - 3800 used as a switch (for igmp snooping - configured with NM16-ESW).

2 VMs - 20012R2 attached to R1 and switch1 via HyperV internal switches.

The configuration basically means enabling PIM dense mode on all interfaces (including the one towards PCs); enabling multicast routing, enable a routing protocol so that every network is reachable (including the PCs)

My mistakes with this simple design:

* not advertising the networks of the PCs

* not enabling PIM towards PC

* I need the command line to specify the TTL - by default it is set to 1 by VLC.

Bellow configuration:

!!! R1 !!!

ip multicast-routing

interface FastEthernet0/0
 description --- To switch ---
 ip address 100.100.100.3 255.255.255.0
 ip pim dense-mode
 speed auto

interface Serial2/1
 description --- To R2 ---
 ip address 23.23.23.3 255.255.255.0
 ip pim dense-mode
 serial restart-delay 0

router eigrp 10
 network 23.23.23.0 0.0.0.255
network 100.100.100.0 0.0.0.255

And on the switch just basic L2 connectivity

Fa1/0                      connected    100        a-full   a-100 10/100BaseTX
Fa1/1                      connected    100        a-full   a-100 10/100BaseTX

From the win machine connected to R1:

vlc -vvv "c:\video\1.mov" --sout "#transcode{vcodec=h264,acodec=mpga,ab=128,channels=2,samplerate=44100} :rtp{dst=224.10.10.10,port=10000,mux=ts,sap,name=test,ttl=10}"

and on the receiver VLC (connected to switch1) - open media stream: rtp://@224.10.10.10:10000

Hth,
