ABSTRACT:
A test monitoring device for detecting a fault in a multicast routing infrastructure includes a processor, a memory coupled with the processor, and a network interface coupled with the processor. The device is configured to send a source configuration request for configuring a device in the infrastructure to be a test packet source, and a receiver configuration request for configuring one or more devices in the infrastructure to be test packet receivers where the test packet source sends out test packets to a predetermined group of test packet receivers. The source configuration request contains an identifier identifying the test monitoring device. The predetermined group has a group identifier. The device is also configured to examine data reports from the test packet receivers relating to a plurality of test packets sent by the test packet source.
