Step 4 Configure the basic MPLS functions on each interface.
# Configure LSRA.
[LSRA] interface gigabitethernet 1/0/0
[LSRA-GigabitEthernet1/0/0] mpls
[LSRA-GigabitEthernet1/0/0] quit
[LSRA] interface gigabitethernet 2/0/0
[LSRA-GigabitEthernet2/0/0] mpls
[LSRA-GigabitEthernet2/0/0] quit
# Configure LSRB.
[LSRB] interface gigabitethernet 1/0/0
[LSRB-GigabitEthernet1/0/0] mpls
[LSRB-GigabitEthernet1/0/0] quit
[LSRB] interface gigabitethernet 2/0/0
[LSRB-GigabitEthernet2/0/0] mpls
[LSRB-GigabitEthernet2/0/0] quit
# Configure LSRC.
[LSRC] interface gigabitethernet 1/0/0
[LSRC-GigabitEthernet1/0/0] mpls
[LSRC-GigabitEthernet1/0/0] quit
[LSRC] interface gigabitethernet 2/0/0
[LSRC-GigabitEthernet2/0/0] mpls
[LSRC-GigabitEthernet2/0/0] quit
# Configure LSRD.
[LSRD] interface gigabitethernet 1/0/0
[LSRD-GigabitEthernet1/0/0] mpls
[LSRD-GigabitEthernet1/0/0] quit
[LSRD] interface gigabitethernet 2/0/0
[LSRD-GigabitEthernet2/0/0] mpls
[LSRD-GigabitEthernet2/0/0] quit
Step 5 Establish a static LSP from LSRA to LSRD.
# Configure the ingress LSRA.
[LSRA] static-lsp ingress RAtoRD destination 4.4.4.9 32 nexthop 10.1.1.2 out-label
20
# Configure the transit LSRB.
[LSRB] static-lsp transit RAtoRD incoming-interface gigabitethernet 1/0/0 in-label
20 nexthop 10.2.1.2 out-label 40
# Configure the egress LSRD.
[LSRD] static-lsp egress RAtoRD incoming-interface gigabitethernet 1/0/0 in-label
40
After the configuration, run the display mpls static-lsp verbose or display mpls lsp command
on the LSRs to view the status of the LSP.
Take the display on LSRA as an example.
[LSRA] display mpls static-lsp
