Field Description
Local label Label assigned by this router.
Outgoing Label or VC
Note This field is not supported on
the Cisco 10000 series
routers.
Label assigned by the next hop or Virtual Path Identifier (VPI)/
Virtual Channel Identifier (VCI) used to get to next hop. The
entries in this column are the following:
• [T]—Means forwarding through an LSP tunnel.
• No Label—Means that there is no label for the destination
from the next hop or that label switching is not enabled on
the outgoing interface.
• Pop Label—Means that the next hop advertised an
implicit NULL label for the destination and that the router
removed the top label.
• Aggregate—Means there are several prefixes for one local
label. This entry is used when IPv6 is configured on edge
routers to transport IPv6 traffic over an IPv4 MPLS
network.
Prefix or Tunnel Id Address or tunnel to which packets with this label are sent.
Note If IPv6 is configured on edge routers to transport IPv6
traffic over an IPv4 MPLS network, “IPv6” is
displayed here.
[V]—means that the corresponding prefix is in a VRF.
Bytes label switched Number of bytes switched with this incoming label. This
includes the outgoing label and Layer 2 header.
Outgoing interface Interface through which packets with this label are sent.
Next Hop IP address of the neighbor that assigned the outgoing label.
Bundle adjacency exp(vcd) Bundle adjacency information. Includes the MPLS EXP value
and the corresponding VCD.
MAC/Encaps Length in bytes of the Layer 2 header and length in bytes of the
packet encapsulation, including the Layer 2 header and label
header.
MTU MTU of the labeled packet.
label Stack All the outgoing labels. If the outgoing interface is transmis-
sion convergence (TC)-ATM, the VCD is also shown.
Note TC-ATM is not supported on Cisco 10000 series
routers.

The actual encapsulation in hexadecimal form. A space is
shown between Layer 2 and the label header.
