CMplsGlobalId
This object contains the Textual Convention of IP based operator unique identifier (Global_ID), the Global_ID can contain the 2-octet or 4-octet value of the operator's Autonomous System Number (ASN). It is expected that the Global_ID will be derived from the globally unique ASN of the autonomous system hosting the PEs containing the actual AIIs. The presence of a Global_ID based on the operator's ASN ensures that the AII will be globally unique. When the Global_ID is derived from a 2-octet AS number, the two high-order octets of this 4-octet identifier MUST be set to zero. Further ASN 0 is reserved. A Global_ID of zero means that no Global_ID is present. Note that a Global_ID of zero is limited to entities contained within a single operator and MUST NOT be used across an NNI. A non-zero Global_ID MUST be derived from an ASN owned by the operator.
