1. 配置VLAN和IP地址
[LSW1]vlan batch 10
[LSW1-GigabitEthernet0/0/2]port link-type trunk
[LSW1-GigabitEthernet0/0/2]port trunk allow-pass vlan 10
[LSW1-Vlanif10]ip add 10.1.1.1 24
[LSW1-LoopBack1]ip add 1.1.1.1 32
[LSW2]vlan batch 10 20
[LSW2-GigabitEthernet0/0/1]port link-type trunk
[LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
[LSW2-GigabitEthernet0/0/3]port link-type trunk
[LSW2-GigabitEthernet0/0/3]port trunk allow-pass vlan 20
[LSW2-Vlanif10]ip add 10.1.1.2 24
[LSW2-Vlanif20]ip add 10.2.1.2 24
[LSW2-LoopBack1]ip add 2.2.2.2 32
[LSW3]vlan batch 20
[LSW3-GigabitEthernet0/0/2]port link-type trunk
[LSW3-GigabitEthernet0/0/2]port trunk allow-pass vlan 20
[LSW3-Vlanif20]ip add 10.2.1.3 24
[LSW3-LoopBack1]ip add 3.3.3.3 32
2. 配置OSPF协议发布各节点接口所连网段和LSR ID的主机路由
[LSW1]ospf 1
[LSW1-ospf-1]area 0
[LSW1-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255
[LSW1-ospf-1-area-0.0.0.0]network 1.1.1.1 0.0.0.0
[LSW2]ospf 1
[LSW2-ospf-1]area 0
[LSW2-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0..255
[LSW2-ospf-1-area-0.0.0.0]network 10.2.1.0 0.0.0.255
[LSW2-ospf-1-area-0.0.0.0]network 2.2.2.2 0.0.0.0
[LSW3]ospf 1
[LSW3-ospf-1]area 0
[LSW3-ospf-1-area-0.0.0.0]network 10.2.1.0 0.0.0.255
[LSW3-ospf-1-area-0.0.0.0]network 3.3.3.3 0.0.0.0
3. 在各节点使能MPLS基本功能
[LSW1]mpls lsr-id 1.1.1.1
[LSW1]mpls
[LSW2]mpls lsr-id 2.2.2.2
[LSW2]mpls
[LSW3]mpls lsr-id 3.3.3.3
[LSW3]mpls
4. 配置各接口的MPLS能力
[LSW1-Vlanif10]mpls
[LSW2-Vlanif10]mpls
[LSW2-Vlanif20]mpls
[LSW3-Vlanif20]mpls
5. 创建从LSW1到LSW3的静态LSP
[LSW1]static-lsp ingress LSP1 destination 3.3.3.3 32 nexthop 10.1.1.2 out-label 20
[LSW2]static-lsp transit LSP1 incoming-interface Vlanif 10 in-label 20 nexthop 10.2.1.3 out-label 30
[LSW3]static-lsp egress LSP1 incoming-interface Vlanif 20 in-label 30
6. 创建从LSW1到LSW3的静态LSP
[LSW3]static-lsp ingress LSP2 destination 1.1.1.1 32 nexthop 10.2.1.2 out-label 40
[LSW2]static-lsp transit LSP2 incoming-interface Vlanif 20 in-label 40 nexthop 10.1.1.1 out-label 50
[LSW1]static-lsp egress LSP2 incoming-interface Vlanif 10 in-label 50
7. 检查配置
