华为设备配置禁止向远端对等体分配标签

1. 配置IP地址

[PE1-GigabitEthernet0/0/0]ip add 10.1.1.1 24

[PE1-LoopBack0]ip add 1.1.1.1 32

[PE2-GigabitEthernet0/0/0]ip add 10.1.2.2 24

[PE2-LoopBack0]ip add 2.2.2.2 32

[PE3-GigabitEthernet0/0/0]ip add 10.1.3.3 24

[PE3-LoopBack0]ip add 3.3.3.3 32

[P-GigabitEthernet0/0/0]ip add 10.1.1.4 24

[P-GigabitEthernet0/0/1]ip add 10.1.2.4 24

[P-GigabitEthernet0/0/2]ip add 10.1.3.4 24

[P-LoopBack0]ip add 4.4.4.4 32

2. 配置IS-IS协议发布各节点接口所连网段和LSR ID的主机路由

[PE1]isis 1

[PE1-isis-1]is-level level-2

[PE1-isis-1]network-entity 86.4501.0010.0100.0001.00

[PE1-GigabitEthernet0/0/0]isis enable 1

[PE1-LoopBack0]isis enable 1

[PE2]isis 1

[PE2-isis-1]is-level level-2

[PE2-isis-1]network-entity 86.4501.0020.0200.0002.00

[PE2-GigabitEthernet0/0/0]isis enable 1

[PE2-LoopBack0]isis enable 1

[PE3]isis 1

[PE3-isis-1]is-level level-2

[PE3-isis-1]network-entity 86.4501.0030.0300.0003.00

[PE3-GigabitEthernet0/0/0]isis enable 1

[PE3-LoopBack0]isis enable 1

[P]isis 1

[P-isis-1]is-level level-2

[P-isis-1]network-entity 86.4501.0040.0400.0004.00

[P-GigabitEthernet0/0/0]isis enable 1

[P-GigabitEthernet0/0/1]isis enable 1

[P-GigabitEthernet0/0/2]isis enable 1

[P-LoopBack0]isis enable 1

3. 配置本地LDP会话

[PE1]mpls lsr-id 1.1.1.1

[PE1]mpls

[PE1]mpls ldp

[PE1-GigabitEthernet0/0/0]mpls

[PE1-GigabitEthernet0/0/0]mpls ldp

[PE2]mpls lsr-id 2.2.2.2

[PE2]mpls

[PE2]mpls ldp

[PE2-GigabitEthernet0/0/0]mpls

[PE2-GigabitEthernet0/0/0]mpls ldp

[PE3]mpls lsr-id 3.3.3.3

[PE3]mpls

[PE3]mpls ldp

[PE3-GigabitEthernet0/0/0]mpls

[PE3-GigabitEthernet0/0/0]mpls ldp

[P]mpls lsr-id 4.4.4.4

[P]mpls

[P]mpls ldp

[P-GigabitEthernet0/0/0]mpls

[P-GigabitEthernet0/0/0]mpls ldp

[P-GigabitEthernet0/0/1]mpls

[P-GigabitEthernet0/0/1]mpls ldp

[P-GigabitEthernet0/0/2]mpls

[P-GigabitEthernet0/0/2]mpls ldp

4. 在PW两端的PE之间要建立MPLS LDP远端对等体关系

[PE1]mpls ldp remote-peer pe2

[PE1-mpls-ldp-remote-pe2]remote-ip 2.2.2.2

[PE1]mpls ldp remote-peer pe3

[PE1-mpls-ldp-remote-pe3]remote-ip 3.3.3.3

[PE2]mpls ldp remote-peer pe1

[PE2-mpls-ldp-remote-pe1]remote-ip 1.1.1.1

[PE3]mpls ldp remote-peer pe1

[PE3-mpls-ldp-remote-pe1]remote-ip 1.1.1.1

5. 在PW两端的PE之间配置禁止向远端对等体分配标签

[PE1]mpls ldp remote-peer pe2

[PE1-mpls-ldp-remote-pe2]remote-ip 2.2.2.2 pwe3

[PE1]mpls ldp remote-peer pe3

[PE1-mpls-ldp-remote-pe3]remote-ip 3.3.3.3 pwe3

[PE2]mpls ldp remote-peer pe1

[PE2-mpls-ldp-remote-pe1]remote-ip 1.1.1.1 pwe3

[PE3]mpls ldp remote-peer pe1

[PE3-mpls-ldp-remote-pe1]remote-ip 1.1.1.1 pwe3
