Configure basic MPLS and MPLS LDP on the MPLS backbone to establish LDP LSPs:
# Configure Spoke-PE 1.
[Spoke-PE1] mpls lsr-id 1.1.1.9
[Spoke-PE1] mpls ldp
[Spoke-PE1-ldp] quit
[Spoke-PE1] interface vlan-interface 4
[Spoke-PE1-Vlan-interface4] mpls enable
[Spoke-PE1-Vlan-interface4] mpls ldp enable
[Spoke-PE1-Vlan-interface4] quit
# Configure Spoke-PE 2.
[Spoke-PE2] mpls lsr-id 3.3.3.9
[Spoke-PE2] mpls ldp
[Spoke-PE2-ldp] quit
[Spoke-PE2] interface vlan-interface 5
[Spoke-PE2-Vlan-interface5] mpls enable
[Spoke-PE2-Vlan-interface5] mpls ldp enable
[Spoke-PE2-Vlan-interface5] quit
# Configure Hub-PE.
[Hub-PE] mpls lsr-id 2.2.2.9
[Hub-PE] mpls ldp
[Hub-PE-ldp] quit
[Hub-PE] interface vlan-interface 4
[Hub-PE-Vlan-interface4] mpls enable
[Hub-PE-Vlan-interface4] mpls ldp enable
[Hub-PE-Vlan-interface4] quit
[Hub-PE] interface vlan-interface 5
[Hub-PE-Vlan-interface5] mpls enable
[Hub-PE-Vlan-interface5] mpls ldp enable
[Hub-PE-Vlan-interface5] quit
After the configurations, LDP sessions are established between Spoke-PE 1, Spoke-PE 2, and
Hub-PE.
Execute the display mpls ldp peer command on the devices. The output shows that the LDP session
status is Operational.
Execute the display mpls ldp lsp command on the devices. The output shows the LSPs established
by LDP.

Configure VPN instances on the Spoke-PEs and Hub-PE:
# Configure Spoke-PE 1.
[Spoke-PE1] ip vpn-instance vpn1
[Spoke-PE1-vpn-instance-vpn1] route-distinguisher 100:1
[Spoke-PE1-vpn-instance-vpn1] vpn-target 111:1 import-extcommunity
[Spoke-PE1-vpn-instance-vpn1] vpn-target 222:2 export-extcommunity
[Spoke-PE1-vpn-instance-vpn1] quit
[Spoke-PE1] interface vlan-interface 2
[Spoke-PE1-Vlan-interface2] ip binding vpn-instance vpn1
[Spoke-PE1-Vlan-interface2] ip address 10.1.1.2 24
