Hi David
Thanks for guiding me how to proceed. I have captured the output result of perf (perf_output_5.10.49).
To confirm the problem, I tested it again on Ubuntu (kernel version is 5.4.0-79) using Docker and the results were the same, the only difference is the kernel version. I also collected the perf results and added them to the attachment (perf_output_5.4.0).
Best Regards
Xiao Jiguang

I see that counter incrementing. Look at the fib6 tracepoints and see what the lookups are returning:
perf record -e fib6:* -a
<run test>
Ctrl-C
