Manual:MPLS

Property
bytes (integer)
Description
Total number of packet bytes matched by this entry
destination (IP/Mask) Destination prefix for which labels are assigned
in-label (integer)
Label number for incoming packet
interface (string)
ldp (yes | no)
Whether labels are LDP signaled
nexthop (IP)
IP address of the nexthop
out-label (integer)
Label number which is added or switched to for outgoing packet.
packets (integer)
Number of packets matched by this entry
traffic-eng (yes | no) Shows whether entry is signaled by RSVP-TE (Traffic Engineering)
vpls (yes | no)
Shows whether entry is used for VPLS tunnels.
For example we have forwarding table as shown below.

[admin@RB493G] /mpls forwarding-table>
You can see that all labels are LDP signaled. Note that for entry #1 there is no out-label, it means that MPLS label
switching will not occur, packet will be sent out as regular IP packet. In the other hand entry #2 has in-label and
out-label, which means that during packet forwarding label will be switched from 120 to 112.
Interface
Sub-menu: /mpls interface
This menu allows to configure MTUs including MPLS headers that interface can forward without fragmentation.
Note: If Ethernet card does not support Jumbo frames, then MPLS MTU for all interfaces on all devices
participating in LSP should be set to 1500
