queue. RCC/LCC logs the same errors (exact match) from different nodes as one error. RCC/LCC compares
the errors based on prefix/label, version number, type of error, etc.
On-demand Scan
In On-demand Scan, user requests scan through the command line interface on a particular prefix in a particular
table or all the prefixes in the table. The scan is run immediately and the results are published right away.
LCC performs on-demand scan on the LSD, where as RCC performs it per VRF.
Background Scan
In Background Scan, user configures the scan that is then left to run in the background. The configuration
consists of the time period for the periodic scan. This scan can be configured on either a single table or multiple
tables. LCC performs background scan on the LSD, where as RCC performs it either for default or other
VRFs.
