Step 2 Configure basic MPLS functions and MPLS LDP on the MPLS backbone network and set up
LDP LSPs.
# Configure PE1.
[PE1] mpls lsr-id 1.1.1.9
[PE1] mpls
[PE1-mpls] quit
[PE1] mpls ldp
[PE1-mpls-ldp] quit
[PE1] interface vlanif 30
[PE1-Vlanif30] mpls
[PE1-Vlanif30] mpls ldp
[PE1-Vlanif30] quit
# Configure the P.
[P] mpls lsr-id 2.2.2.9
[P] mpls
[P-mpls] quit
[P] mpls ldp
[P-mpls-ldp] quit
[P] interface vlanif 30
[P-Vlanif30] mpls
[P-Vlanif30] mpls ldp
[P-Vlanif30] quit
[P] interface vlanif 60
[P-Vlanif60] mpls
[P-Vlanif60] mpls ldp
[P-Vlanif60] quit
# Configure PE2.
[PE2] mpls lsr-id 3.3.3.9
[PE2] mpls
[PE2-mpls] quit
[PE2] mpls ldp
[PE2-mpls-ldp] quit
[PE2] interface vlanif 60
[PE2-Vlanif60] mpls
[PE2-Vlanif60] mpls ldp
[PE2-Vlanif60] quit
After the configuration, LDP sessions are established between PE1 and P, and between P and
PE2. By running the display mpls ldp session command, you can see that the status of the LSP
sessions is Operational. By running the display mpls ldp lsp command, you can see the
establishment status of the LDP LSP.
Take PE1 for example.
