Field Description
vcid The virtual circuit identifier assigned to one of the interfaces on the
device.
type The forwarding mode used.
local groupid The ID used to group VCs locally. EoMPLS groups VCs by the
hardware port, which is unique for each port on a device.
remote groupid The ID used by the peer to group several VCs.
vc is up
or
vc is down
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.
client The ingress or egress interface through which the Layer 2 VLAN
packet travels. The interface is a VLAN or physical interface.
destination The destination specified for this VC. You specify the destination IP
address as part of the mpls l2transport route interface configuration
command.
Peer LDP Ident The LDP IP address of the targeted peer.
local 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 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 with the egress interface.
Outgoing interface The egress interface of the VC.
Next hop The IP address of the next hop.
Local MTU The maximum transmission unit specified for the client interface.
Remote MTU The maximum transmission unit specified for the remote device client
interface.
