Tracing Neighbor Discovery Protocol Traffic
You can trace various Neighbor Discovery protocol traffic to help debug Neighbor Discovery protocol issues. To trace Neighbor Discovery protocol traffic include the traceoptions statement at the [edit protocols router-advertisement] hierarchy level:
traceoptions {file filename <files number> <size size> <world-readable |
no-world-readable>;flag flag <flag-modifier> <disable>;}
Global tracing options are inherited from the configuration set by the traceoptions statement at the [edit routing-options] hierarchy level. You can override the following global trace options for the Neighbor Discovery protocol using the traceoptions flag statement included at the [edit protocols router-advertisement] hierarchy level:
- all—All tracing operations
- general—All normal operations and routing table changes (a combination of the normal and route trace operations)
- normal—Normal events
- policy—Policy processing
- route—Routing information
- state—State transitions
- task—Routing protocol task processing
- timer—Routing protocol timer processing
 | Note: Use the trace flag all with caution as this may cause the CPU to become very busy. |
