-The debugging subsystem for PIMv6 behaves in accordance with how FRR handles
-debugging. You can specify debugging at the enable CLI mode as well as the
-configure CLI mode. If you specify debug commands in the configuration cli
-mode, the debug commands can be persistent across restarts of the FRR pim6d if
-the config was written out.
