A route to the destination address of the LSP must be available on the ingress node, but it is not
needed on transit and egress nodes. Therefore, you do not need to configure a routing protocol to
ensure IP connectivity among all switches.
Configuration procedure
1.
Create VLANs and configure IP addresses for all interfaces, including the loopback interfaces, as
. (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.
