7.27 BGP Bestpath Selection - DMZ Link Bandwidth

During this scenario, I got the message below after clear ip bgp * soft done.



*Mar  1 11:27:45.373: %FIB-4-UNEQUAL: Range of unequal path weightings too large for prefix 28.119.16.0/24. Some available paths may not be used.


Example output below is not related to 28.119.16.0/24 prefix, however, the output should be same (I also confirmed it with 28.119.16.0/24). After modifying bandwidth on R6, the error message has not shown up anymore.
