VC State The state of the VC (UP or DOWN):
UP—The VC can carry traffic between the two VC end points. A VC
is up when both the local and remote interfaces are programmed.
• The local interface is programmed if the VC is configured and the
client interface is up.
• The remote interface is programmed if the remote interface is
configured and there is a VC remote VC label and an IGP label.
The IGP label means that there is a label-switched path (LSP) to
the peer.
DOWN—The VC is not ready to carry traffic between the two VC end
points.
Trans Type The forwarding mode used.
Local VC Label The VC label that a device signals to its peer device. The local VC label
determines the egress interface of a packet arriving from the MPLS
backbone.
Remote VC Label The VC label of the remote peer device.
Tunnel Label An IGP label used to route the packet over the MPLS backbone to the
destination device that has the egress interface.
