MPLS VC labels Local VC label is a disposition label, which determines the egress interface of
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
description
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 disabled.
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—The provider (P) router is absent and the tunnel label is not to be
used. Alternatively, imp-null can signify traffic engineering tunnels
between the PE routers.
unassigned—The label has not been assigned.
no route—The label is not in the routing table.
no adjacency—The adjacency for the next hop is missing.
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.
not ready, Cisco Express Forwarding disabled—Cisco Express Forwarding
is disabled.
not ready, label forwarding information base (LFIB) disabled—The MPLS
switching subsystem is disabled.
not ready, LFIB entry present—The tunnel label exists in the LFIB, but the
VC is down.
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
Route Processor [RP], and received on the standby RP).
SSM
segment/switch IDs
The IDs used to refer to the control plane and data plane contexts for this VC.
This data is not for customer use but for Cisco personnel for troubleshooting
purposes. When the source specific multicast (SSM) IDs are followed by the
word “used,” the checkpointed data has been successfully sent and not released.
PWID The PW ID used in the data plane to correlate the switching context for the
segment mentioned with the MPLS switching context. This data is not for
customer use but for Cisco personnel for troubleshooting purposes.
packet totals Number of packets sent and received. Received packets are those AToM packets
received from the MPLS core. Sent packets are those AToM packets sent to the
MPLS core. This number does not include dropped packets.
