LDP and IGP linkage refers to the release of IGP and TD routes to ensure that LDP and IGP linkage complete network efficiency, so that KGP and LDP maintains a consistent path, minimizing traffic loss, thereby improving the reliability of the entire network.

The statement, despite some apparent typographical errors (e.g., "KGP" for IGP), correctly describes the fundamental purpose of LDP-IGP Synchronization. This feature ensures that an IGP (like OSPF or IS-IS) does not use a link for forwarding traffic until the LDP session over that link is fully established and labels have been exchanged. This synchronization prevents traffic from being black-holed, which can occur if the IGP converges faster than LDP. By aligning the IGP routing state with the LDP label forwarding state, it maintains a consistent forwarding path, minimizes traffic loss during network reconvergence, and enhances overall network reliability.

This is a True/False question. The statement is fundamentally correct in its description of the goal and outcome of LDP-IGP synchronization, making the "False" option incorrect.

Huawei HCIE-Datacom V1.0 Training Material, "MPLS LDP". The section on LDP-IGP Synchronization explains that the feature is designed to "prevent traffic loss that may occur when IGP converges faster than LDP." It details how IGP is notified to use a link only after the LDP session is established, ensuring consistency between the IP forwarding table and the label forwarding table.

RFC 5443, "LDP IGP Synchronization", Section 1, states: "This document describes a mechanism to address a problem that arises from the fact that the IGP and LDP protocols are not synchronized with each other... This lack of synchronization can cause traffic to be dropped."
