[LSR6-ospf-1-area-0.0.0.0]mpls-te enable

5. 在入节点LSR1上创建主CR-LSP的MPLS TE Tunnel

[LSR1]explicit-path pp1  //配置主CR-LSP的显式路径

[LSR1-explicit-path-pp1]next hop 20.1.1.2

[LSR1-explicit-path-pp1]next hop 20.1.2.3

[LSR1-explicit-path-pp1]next hop 20.1.3.4

[LSR1-explicit-path-pp1]next hop 4.4.4.4

[LSR1]int Tunnel 0/0/1  //配置主CR-LSP的MPLS TE隧道接口

[LSR1-Tunnel0/0/1]ip address unnumbered interface LoopBack 0

[LSR1-Tunnel0/0/1]tunnel-protocol mpls te

[LSR1-Tunnel0/0/1]destination 4.4.4.4

[LSR1-Tunnel0/0/1]mpls te tunnel-id 100

[LSR1-Tunnel0/0/1]mpls te path explicit-path pp1

[LSR1-Tunnel0/0/1]mpls te fast-reroute  //使能TE FRR

[LSR1-Tunnel0/0/1]mpls te commit

华为设备配置TE FRR与备份CR-LSP同步_华为_02

6. 在作为PLR的LSR2上配置Bypass CR-LSP

[LSR2]explicit-path bp1  //配置Bypass CR-LSP的显式路径

[LSR2-explicit-path-bp1]next hop 20.1.4.5

[LSR2-explicit-path-bp1]next hop 20.1.5.3

[LSR2-explicit-path-bp1]next hop 3.3.3.3

[LSR2]int Tunnel 0/0/2  //配置Bypass CR-LSP的隧道接口

[LSR2-Tunnel0/0/2]ip add unnumbered interface LoopBack 0  

[LSR2-Tunnel0/0/2]tunnel-protocol mpls te

[LSR2-Tunnel0/0/2]destination 3.3.3.3

[LSR2-Tunnel0/0/2]mpls te tunnel-id 300

[LSR2-Tunnel0/0/2]mpls te path explicit-path bp1

[LSR2-Tunnel0/0/2]mpls te bypass-tunnel

[LSR2-Tunnel0/0/2]mpls te protected-interface g0/0/1  ////将Bypass CR-LSP绑定到被保护的接口

[LSR2-Tunnel0/0/2]mpls te commit

华为设备配置TE FRR与备份CR-LSP同步_华为_03


华为设备配置TE FRR与备份CR-LSP同步_华为_04

华为设备配置TE FRR与备份CR-LSP同步_MPLS_05

可以看到旁路隧道绑定到出接口g0/0/1目前未被使用

7. 在入节点LSR1上创建普通备份CR-LSP的MPLS TE Tunnel

[LSR1]explicit-path bp2  //配置备份CR-LSP的显式路径

[LSR1-explicit-path-bp2]next hop 20.1.6.6

[LSR1-explicit-path-bp2]next hop 20.1.7.3

[LSR1-explicit-path-bp2]next hop 20.1.3.4

[LSR1-explicit-path-bp2]next hop 4.4.4.4

[LSR1]int Tunnel 0/0/1  //配置LSRA的备份CR-LSP

[LSR1-Tunnel0/0/1]mpls te backup ordinary  

[LSR1-Tunnel0/0/1]mpls te path explicit-path bp2 secondary  

[LSR1-Tunnel0/0/1]mpls te commit

8. 在主CR-LSP的入节点配置TE FRR与备份CR-LSP同步

[LSR1]int Tunnel 0/0/1

[LSR1-Tunnel0/0/1]mpls te backup frr-in-use  

[LSR1-Tunnel0/0/1]mpls te commit

华为设备配置TE FRR与备份CR-LSP同步_网络_06

9. 检查配置

[LSR2-GigabitEthernet0/0/1]shutdown  //使LSR2上被保护的出接口失效

华为设备配置TE FRR与备份CR-LSP同步_网络_07

可以看到隧道状态为“Up”，说明主隧道处于Frr-in-use状态的同时，正在创建普通备份的CR-LSP和恢复主CR-LSP
