3. Enable MPLS and LDP:
# Configure Switch A.
[SwitchA] mpls lsr-id 1.1.1.9
[SwitchA] mpls ldp
[SwitchA-ldp] quit
[SwitchA] interface vlan-interface 2
[SwitchA-Vlan-interface2] mpls enable
[SwitchA-Vlan-interface2] mpls ldp enable
[SwitchA-Vlan-interface2] quit
# Configure Switch B.
[SwitchB] mpls lsr-id 2.2.2.9
[SwitchB] mpls ldp
[SwitchB-ldp] quit
[SwitchB] interface vlan-interface 2
