This object indicates the LSP ID of the dynamic decap tunnel, as the description states, the egress-side counterpart to the LSP ID tracked on dynamic ingress tunnels. It distinguishes between successive signaled instances of the same egress LSP, which matters when a tunnel is torn down and resignaled after a path change and an admin needs to confirm exactly which LSP generation is currently terminating traffic at this router. For example, an instance value of 2 confirms this decap entry corresponds to the second signaled instance of the LSP, established after the first instance was torn down following a link failure elsewhere in the path.
