This counter tallies packets this router has re-forwarded downstream after label-swapping for a dynamically-signaled transit LSP, again gated to platforms that support per-tunnel transit accounting. Because transit tunnels often aggregate several customers' traffic onto one LSP, a sudden plateau in this counter while the incoming-packet counter on the same row keeps climbing points to congestion or a drop specific to this tunnel's egress interface on this node. For example, outgoing packets stalling at 2,004,551 for several polling cycles while incoming keeps rising would flag a downstream queue problem tied to this particular LSP.
