# By running the display ip routing-table command on the PEs, you can see that the PEs can
learn the routes of each other's Loopback1 interface.
# Take the display on PE1 as an example:
[PE1] display ip routing-table

Step 2 Enable the basic MPLS capability on the MPLS backbone and establish an LDP LSP.
NOTE
The PE devices are directly connected In this example, you need to run label advertise command to enables
the egress node to assign labels normally to the penultimate hop.

# After the configuration, an LDP LSP can be set up between PE1 and PE2. By running the
display tunnel-info all command, you can see the LSP destined for the address 2.2.2.2. By
running the display mpls ldp lsp command, you can view the LSP information.
