Label-Switched Interface Traffic Statistics Field

When you use the vrf-table-label statement to configure a VRF routing table, a label-switched interface (LSI) logical interface label is created and mapped to the VRF routing table.

Any routes present in a VRF routing table and configured with the vrf-table-label statement are advertised with the LSI logical interface label allocated for the VRF routing table. When packets for this VPN arrive on a core-facing interface, they are treated as if the enclosed IP packet arrived on the LSI interface and are then forwarded and filtered based on the correct table. For more information on the vrf-table-label statement, including a list of supported interfaces, see the JUNOS VPNs Configuration Guide.

If you configure the family mpls statement at the [edit interfaces interface-name unit logical-unit-number] hierarchy level and you also configure the vrf-table-label statement at the [edit routing-instances routing-instance-name] hierarchy level, the output for the show interface interface-name extensive command includes the following output fields about the LSI traffic statistics:

Input bytes—Number of bytes entering the LSI and the current throughput rate in bits per second (bps).
Input packets—Number of packets entering the LSI and the current throughput rate in packets per second (pps).

The following example shows the LSI traffic statistics that you might see as a part of the output of the show interface interface-name extensive command:



Label-switched interface (LSI) traffic statistics:
   Input  bytes:                        0                 0
bps
   Input  packets:                    0                 0
pps
