Configuration procedure
1. Create VLANs and configure IP addresses for all interfaces, including the loopback interfaces,
as shown in Figure 8. (Details not shown.)
2. Configure a static route to the destination address of each LSP:
# On Switch A, configure a static route to network 21.1.1.0/24.
<SwitchA> system-view
[SwitchA] ip route-static 21.1.1.0 24 10.1.1.2
# On Switch C, configure a static route to network 11.1.1.0/24.
<SwitchC> system-view
[SwitchC] ip route-static 11.1.1.0 255.255.255.0 20.1.1.1
3. Configure basic MPLS on the switches:
# Configure Switch A.
[SwitchA] mpls lsr-id 1.1.1.9
[SwitchA] interface vlan-interface 2
[SwitchA-Vlan-interface2] mpls enable
[SwitchA-Vlan-interface2] quit
# Configure Switch B.
[SwitchB] mpls lsr-id 2.2.2.9
[SwitchB] interface vlan-interface 2
[SwitchB-Vlan-interface2] mpls enable
[SwitchB-Vlan-interface2] quit
[SwitchB] interface vlan-interface 3
[SwitchB-Vlan-interface3] mpls enable
[SwitchB-Vlan-interface3] quit
# Configure Switch C.
[SwitchC] mpls lsr-id 3.3.3.9
[SwitchC] interface vlan-interface 3
[SwitchC-Vlan-interface3] mpls enable
[SwitchC-Vlan-interface3] quit
4. Configure a static LSP from Switch A to Switch C:
# Configure the LSP ingress node, Switch A.
[SwitchA] static-lsp ingress AtoC destination 21.1.1.0 24 nexthop 10.1.1.2 out-label
30
# Configure the LSP transit node, Switch B.
[SwitchB] static-lsp transit AtoC in-label 30 nexthop 20.1.1.2 out-label 50
# Configure the LSP egress node, Switch C.
[SwitchC] static-lsp egress AtoC in-label 50
5. Configure a static LSP from Switch C to Switch A:
# Configure the LSP ingress node, Switch C.
[SwitchC] static-lsp ingress CtoA destination 11.1.1.0 24 nexthop 20.1.1.1 out-label
40
# Configure the LSP transit node, Switch B.
[SwitchB] static-lsp transit CtoA in-label 40 nexthop 10.1.1.1 out-label 70
# Configure the LSP egress node, Switch A.
[SwitchA] static-lsp egress CtoA in-label 70
