6.21 Configuring the NQA MTrace Test to Check the RPF
Path from the Multicast Source to the Querier
This section describes how to configure a Multicast Traceroute (MTrace) test to check the
Reserved Path Forwarding (RPF) path from the multicast source to the querier.
6.21.1 Establishing the Configuration Task
Before configuring an MTrace test for the RPF path from the multicast source to the querier,
familiarize yourself with the applicable environment, complete the pre-configuration tasks, and
obtain the required data. This can help you complete the configuration task quickly and
accurately.
6.21.2 Creating an NQA MTrace Test
This part describes how to configure an MTrace instance before performing the MTrace test for
the RPF path from the multicast source to the querier.
6.21.3 Configuring the NQA MTrace Test
This part describes how to set parameters for the MTrace test for the RPF path from the multicast
source to the querier.
6.21.4 (Optional) Adjusting the Performance of the NQA MTrace Test
This part describes how to set optional MTrace test parameters according to the network
operating status.
6.21.5 Starting the NQA MTrace Test
This part describes how to start the MTrace test instance to perform the MTrace test for the RPF
path from the multicast source to the querier.
6.21.6 Checking the Configuration
After performing the MTrace test for the RPF path from the multicast source to the querier, you
can view the test result.
6.21.1 Establishing the Configuration Task
Before configuring an MTrace test for the RPF path from the multicast source to the querier,
familiarize yourself with the applicable environment, complete the pre-configuration tasks, and
obtain the required data. This can help you complete the configuration task quickly and
accurately.
Applicable Environment
To check the Reverse Path Forwarding (RPF) path from the multicast source to the querier, you
can perform the NQA MTrace test.
By performing the MTrace test, you can obtain the possible transmission path of multicast
packets. During the test, actual multicast data flows are not required.
The MTrace test can be used in multicast troubleshooting and routine maintenance to locate the
faulty nodes and reduce configuration errors.
Pre-configuration Tasks
Before configuring the MTrace test, you must enable the multicast function in the network.
