Step 3 Configure the basic MPLS capabilities on the MPLS backbone network.
# Enable MPLS, and set LSR-ID as the IP address of the Loopback1 interface. Enable MPLS
and MPLS LDP on interfaces on the backbone network.
# Configure PE1.
[PE1] mpls lsr-id 1.1.1.1
[PE1] mpls
[PE1-mpls] quit
[PE1] mpls ldp
[PE1-mpls-ldp] quit
[PE1] interface vlanif 20
[PE1-Vlanif20] mpls
[PE1-Vlanif20] mpls ldp
[PE1-Vlanif20] quit
[PE1] interface vlanif 30
[PE1-Vlanif30] mpls
[PE1-Vlanif30] mpls ldp
[PE1-Vlanif30] quit
# The configuration procedures of P1, P2, PE2, and PE3 are the same as the configuration
procedure of PE1 and are not mentioned.
After the configuration, run the display tunnel-info all command on PEs. You can see that
MPLS LSPs are set up between PE1 and PE2, and between PE1 and PE3.
Take the display on PE1 for example.
<PE1> display tunnel-info all
* -> Allocated VC Token
Tunnel ID

0x10023
0x10024
0x10025
0x10026
0x10027
Run the display mpls ldp session command on PE, and you can see that the LDP peer relation
between the PE and the neighboring P is in Operational state.
Take the display on PE1 for example.
<PE1> display mpls ldp session
LDP Session(s) in Public Network
Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM)
A '*' before a session means the session is being deleted.
------------------------------------------------------------------------------
Peer-ID
------------------------------------------------------------------------------
2.2.2.2:0
3.3.3.3:0
------------------------------------------------------------------------------
TOTAL: 2 session(s) Found.
Step 4 Set up a remote LDP session between PEs.
# Configure remote LDP sessions and set their IP addresses as the addresses of the loopback
interfaces on LDP remote peers.
