Cisco IOS Multiprotocol Label Switching Command Reference
January 2010
Tunnel label An IGP label used to route the packet over the MPLS backbone to the
destination router with the egress interface. The first part of the output
displays the type of label. The second part of the output displays the route
information.
The tunnel label information can display any of the following states:
• imp-null: Implicit null means that the provider (P) router is absent and
the tunnel label will not be used. Alternatively, imp-null can signify
traffic engineering tunnels between the PE routers.
• no adjacency: The adjacency for the next hop is missing.
• no route: The label is not in the routing table.
• not ready, Cisco Express Forwarding disabled: Cisco Express
Forwarding is disabled.
• not ready, LFIB entry present: The tunnel label exists in the Label
Forwarding Information Base (LFIB), but the VC is down.
• not ready, LFIB disabled: The MPLS switching subsystem is disabled.
• not ready, no route: An IP route for the peer does not exist in the routing
table.
• not ready, not a host table: The route in the routing table for the remote
peer router is not a host route.
• unassigned: The label has not been assigned.
Create time The time (in hours, minutes, and seconds) when the VC was provisioned.
last status change time Last time (in hours, minutes, and seconds) the VC state changed.
Signaling protocol Type of protocol used to send the MPLS labels on dynamically configured
co
nnections. The output also shows the status of the peer router. For AToM
statically configured pseudowires, the field indicates Manual, because there
is no exchange of labels using a directed control protocol such as LDP.
MPLS VC labels Local VC label is a disposition label, which determines the egress interface
o
f an arriving packet from the MPLS backbone. The remote VC label is a
disposition VC label of the remote peer router.
Group ID Local group ID is used to group VCs locally. The remote group ID is used
by
the peer to group several VCs.
MTU Maximum transmission unit specified for the local and remote interfaces.
Remote interface
de
scription
Interface on the remote router that has been enabled to transmit and receive
Layer 2 packets.
Sequencing Indicates whether sequencing of out-of-order packets is enabled or
di
sabled.
SSO Descriptor Identifies the VC for which the information was checkpointed.
local label The value of the local label that was checkpointed (that is, sent on the active
R
oute Processor [RP], and received on the standby RP).
