Identify and Clear Label Discrepancy

During configuring or de-configuring static labels or a label range, a label discrepancy can get generated
when:
• A static label is configured for an IP prefix that already has a binding with a dynamic label.
• A static label is configured for an IP prefix, when the same label value is dynamically allocated to another
Verification
Identify label discrepancy by using these show commands.
