Multicast traffic generator

Unanswered Question
Jul 25th, 2007

Hi All,

Is there a way I can run multicast traffic generation on a router? I.E. A software piece, a configuration ect. I have routers but want to generate traffic for them, so I can practice multicast labs effectivly.



I have this problem too.

Aside from some routing protocols, no, nothing substantial.

For some classes, we used stuff like iTunes or other music multicaster on a scrap machine. The reward for properly configuring your router was that you could receive music ...

Some of the Video / webcam software should be able to put out some MC frame as well.

Good Luck

Check out the rtr or ip sla commands, depending on which IOS version you are using. They can be used to generate a constant stream of traffic.

A simple "ping repeat 10" works for quick checks, too.

Yes, you can use MRM (multicast routing monitor) for this purpose. It is described in the IP Multicast Configuration Guide:

The benefits of the MRM are as follows:

*MRM allows network personnel to generate test flows without having to use host devices.

*MRM can verify a multicast environment prior to an event. You need not wait for real multicast traffic to fail in order to find out that a problem exists. You can test the multicast routing environment before a planned event.

*MRM provides easy diagnostics. The error information is easy for the user to understand.

*MRM is scalable. This diagnostic tool works well for many users.
