Step 3 Configure basic MPLS functions, enable MPLS LDP, and establish LDP LSPs on the MPLS
backbone network.
# 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 10
[PE1-Vlanif10] mpls
[PE1-Vlanif10] mpls ldp
# Configure P.
[P] mpls lsr-id 2.2.2.9
[P] mpls
[P-mpls] quit
[P] mpls ldp
[P-mpls-ldp] quit
[P] interface vlanif 10
[P-Vlanif10] mpls
[P-Vlanif10] mpls ldp
[P-Vlanif10] quit
[P] interface vlanif 20
[P-Vlanif20] mpls
[P-Vlanif20] mpls ldp
[P-Vlanif20] 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 20
[PE2-Vlanif20] mpls
[PE2-Vlanif20] mpls ldp
[PE2-Vlanif20] quit
After the configuration, LDP sessions should be set up between PE1 and P, and between PE2
and P. Running the display mpls ldp session command, you can see that Status is
Operational. Run the display mpls ldp lsp command, and you can see the establishment status
of the LDP LSP.
Take the display on PE1 as an example.
