配置静态BFD检测静态LSP

[r1]int g0/0/0[r1-GigabitEthernet0/0/0]ip address 12.1.1.1 24

配置OSPF协议：

[r1]ospf 100[r1-ospf-100]area 0[r1-ospf-100-area-0.0.0.0]network 1.1.1.1 0.0.0.0 [r1-ospf-100-area-0.0.0.0]network 12.1.1.0 0.0.0.255[r1-ospf-100-area-0.0.0.0]network 14.1.1.0 0.0.0.255

配置节点使用MPLS功能：

[r1]mpls lsr-id 1.1.1.1[r1]mpls

配置接口使用MPLS功能：

[r1]int g0/0/0[r1-GigabitEthernet0/0/0]mpls [r1]int g0/0/1[r1-GigabitEthernet0/0/1]mpls

配置静态LSP 1与LSP 2：

[r1]static-lsp ingress lsp1 destination 3.3.3.3 32 nexthop 12.1.1.2 out-label 20[r2]static-lsp transit lsp1 incoming-interface g0/0/0 in-label 20 nexthop 23.1.1.2 out-label 40[r3]static-lsp egress lsp1 incoming-interface g0/0/1 in-label 40[r1]static-lsp ingress lsp2 destination 3.3.3.3 32 nexthop 14.1.1.2 out-label 30[r4]static-lsp transit lsp2 incoming-interface g0/0/1 in-label 30 nexthop 34.1.1.1 out-label 60[r3]static-lsp egress lsp2 incoming-interface g0/0/0 in-label 60

配置BFD检测静态LSP 1：

[r1]bfd[r1-bfd]quit[r1]bfd peltope2 bind static-lsp lsp1[r1-bfd-lsp-session-peltope2]discriminator local 1[r1-bfd-lsp-session-peltope2]discriminator remote 2[r1-bfd-lsp-session-peltope2]min-rx-interval 100[r1-bfd-lsp-session-peltope2]min-tx-interval 100[r1-bfd-lsp-session-peltope2]process-pst [r1-bfd-lsp-session-peltope2]commit [r3]bfd[r3-bfd]quit[r3]bfd pe2tope1 bind peer-ip 1.1.1.1[r3-bfd-session-pe2tope1]discriminator local 2[r3-bfd-session-pe2tope1]discriminator remote 1[r3-bfd-session-pe2tope1]min-rx-interval 100[r3-bfd-session-pe2tope1]min-tx-interval 100[r3-bfd-session-pe2tope1]commit
