After the configuration, run the display ip routing-table command on U-PE, P, or S-PE, and
you can see that the devices can learn each other's routes. Take the display on S-PE for example.
<S-PE> display ip routing-table

The U-PEs can ping each other. Take the display on U-PE1 for example.
<U-PE1> ping 40.1.1.2
PING 40.1.1.2: 56 data bytes, press CTRL_C to break
Reply from 40.1.1.2: bytes=56 Sequence=1 ttl=252 time=160 ms

Step 4 Enable MPLS and set up LSPs and LDP sessions.
Configure the basic MPLS capability on the MPLS backbone network. Set up tunnels and LDP
sessions between U-PE1 and S-PE, and between S-PE and U-PE2.
# Configure U-PE1.
[U-PE1] mpls lsr-id 1.1.1.9
[U-PE1] mpls
[U-PE1-mpls] quit
[U-PE1] mpls ldp
[U-PE1-mpls-ldp] quit
[U-PE1] interface vlanif 20
[U-PE1-Vlanif20] mpls
[U-PE1-Vlanif20] mpls ldp
[U-PE1-Vlanif20] quit
[U-PE1] mpls ldp remote-peer 3.3.3.9
[U-PE1-mpls-ldp-remote-3.3.3.9] remote-ip 3.3.3.9
[U-PE1-mpls-ldp-remote-3.3.3.9] quit
# Configure P1.
[P1] mpls lsr-id 2.2.2.9
[P1] mpls
[P1-mpls] quit
[P1] mpls ldp
