Hi All, I wanted to pass this along as a useful tool for generating multicast traffic in an environment without the need of a physical host. After some googling, I ran across MRM at the bottom of the 12.4T configuration guide and it works like a charm.
Essentially you define a router interface as a source, and define any number of interfaces in your lab as receivers as well as a management router. The management router kicks off the test and tells your defined source interface to generate the configured multicast stream as well as signaling all your defined receiving interfaces to send IGMP reports. the management router also gathers flow statistics such as packet loss. But the big benefit is having the ability use any router to generate legitimate UDP or RTP multicast traffic and observe the behavior of your multicast routing topology. After some testing in dynamips, the functionality mostly works except the multicast traffic will get dropped at the source router. PIM Registers, Joins and IGMP reports still work, however. http://www.cisco.com/en/US/docs/ios/ipmulti/configuration/guide/imc_routing_monitor_ps6441_TSD_Products_Configuration_Guide_Chapter.html I hope this isn't redundant information.
