The follows figure shows the structure of an ILM that swaps label from 100 to 200

for prefix FEC 172.18.10.0/24.

Example The following example shows how to configure a static ILM that swaps the label

from 100 to 200 for prefix FEC 172.18.10.0/24 at transit SLR.

The following example shows how to configure a static ILM that pop label from

100 for prefix FEC 172.18.10.0/24 at egress LER.

The following example shows how to configure a static ILM that swaps label from

300 to 3 for prefix FEC 172.18.10.0/24 at transit LSR. (This example is for PHP

mode).

The user can verify their settings by entering show mpls forwarding-table

command.

Note: When the user wants to configure "swap-label <16-1048575> 3". It means

the P operation, and the user should not configure QinQ in the P router.
