These extensions allow vendors to incorporate\nproprietary data within PCEP messages, facilitating enhanced network\noptimization and functionality in environments requiring\nvendor-specific features. The extensions maintain compatibility with\nexisting PCEP implementations and promote interoperability across\ndiverse network deployments. RFC 7470 defines a facility to carry\nvendor-specific information in stateless PCEP messages. This document\nextends this capability for the stateful PCEP messages.\r\n\r\nThis document updates RFC 7470 to specify that Enterprise Numbers are\nmanaged through the \"Private Enterprise Numbers (PENs)\" registry.","pub_date":"April 2025","keywords":["PCE","vendor specific","vendor-specific"],"obsoletes":[],"obsoleted_by":[],"updates":["RFC7470"],"updated_by":[],"see_also":[],"doi":"10.17487\/RFC9752","errata_url":null}
