Major network vendors (except Cisco) default to the following modes of Label Distribution Protocol (LDP) operation (as per RFC 5036 LDP Specification):

  • Label Distribution (Advertisement): Downstream Unsolicited (section 2.6.3)
  • Label Control: Ordered (section 2.6.1)
  • Label Retention: Liberal (section 2.6.2)

This topic focuses on Ordered Label Distribution Control procedure to help you better understand when LSR actually assigns labels and initiates transmission of a label mapping.
