This object holds the new label value this router swaps in before forwarding a matched frame to the next hop, the classic MPLS label-swap operation performed at a transit router, as the description states. A mismatch between this outgoing value and whatever the downstream hop expects as its own incoming label breaks the LSP mid-path, even though the tunnel might show as operationally up on this router alone. For example, swapping an incoming label of 100024 for an outgoing label of 200031 before forwarding toward the next transit or egress router requires that downstream router's incoming-label configuration to match 200031 exactly.
