华为设备配置LDP LSP建立的触发策略示例（Transit）_网络

1. 配置IP地址

[LSR1-GigabitEthernet0/0/0]ip add 10.1.1.1 24

[LSR1-LoopBack0]ip add 1.1.1.1 32

[LSR2-GigabitEthernet0/0/1]ip add 10.1.1.2 24

[LSR2-GigabitEthernet0/0/0]ip add 10.1.2.2 24

[LSR2-LoopBack0]ip add 2.2.2.2 32

[LSR3-GigabitEthernet0/0/0]ip add 10.1.2.3 24

[LSR3-GigabitEthernet0/0/1]ip add 10.1.3.3 24

[LSR3-LoopBack0]ip add 3.3.3.3 32

[LSR4-GigabitEthernet0/0/0]ip add 10.1.3.4 24

[LSR4-LoopBack0]ip add 4.4.4.4 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

[LSR1]ospf 1

[LSR1-ospf-1]area 0

[LSR1-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255

[LSR1-ospf-1-area-0.0.0.0]network 1.1.1.1 0.0.0.0

[LSR2]ospf 1

[LSR2-ospf-1]area 0

[LSR2-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255

[LSR2-ospf-1-area-0.0.0.0]network 10.1.2.0 0.0.0.255

[LSR2-ospf-1-area-0.0.0.0]network 2.2.2.2 0.0.0.0

[LS[LSR3]ospf 1

[LSR3-ospf-1]area 0

[LSR3-ospf-1-area-0.0.0.0]network 10.1.2.0 0.0.0.255

[LSR3-ospf-1-area-0.0.0.0]network 10.1.3.0 0.0.0.255

[LSR3-ospf-1-area-0.0.0.0]network 3.3.3.3 0.0.0.0

[LSR4]ospf 1

[LSR4-ospf-1]area 0

[LSR4-ospf-1-area-0.0.0.0]network 10.1.3.0 0.0.0.255

[LSR4-ospf-1-area-0.0.0.0]network 4.4.4.4 0.0.0.0

3. 配置节点和接口的MPLS及MPLS LDP基本能力

[LSR1]mpls lsr-id 1.1.1.1

[LSR1]mpls

[LSR1]mpls ldp

[LSR1-GigabitEthernet0/0/0]mpls

[LSR1-GigabitEthernet0/0/0]mpls ldp

[LSR2]mpls lsr-id 2.2.2.2

[LSR2]mpls

[LSR2]mpls ldp

[LSR2-GigabitEthernet0/0/1]mpls

[LSR2-GigabitEthernet0/0/1]mpls ldp

[LSR2-GigabitEthernet0/0/0]mpls

[LSR2-GigabitEthernet0/0/0]mpls ldp

[LSR3]mpls lsr-id 3.3.3.3

[LSR3]mpls

[LSR3]mpls ldp

[LSR3-mpls-ldp]q

[LSR3-GigabitEthernet0/0/0]mpls

[LSR3-GigabitEthernet0/0/0]mpls ldp

[LSR3-GigabitEthernet0/0/1]mpls

[LSR3-GigabitEthernet0/0/1]mpls ldp

[LSR4]mpls lsr-id 4.4.4.4

[LSR4]mpls

[LSR4]mpls ldp

[LSR4-GigabitEthernet0/0/0]mpls

[LSR4-GigabitEthernet0/0/0]mpls ldp

4. 在LSR2和LSR3上配置IP前缀列表及使用此IP前缀列表对用于LSP的路由进行过滤：只允许LSR1上的1.1.1.1/32和LSR4上的4.4.4.4/32来建立LSP

[LSR2]ip ip-prefix font permit 1.1.1.1 32

[LSR2]ip ip-prefix font permit 4.4.4.4 32

[LSR2]mpls ldp

[LSR2-mpls-ldp]propagate mapping for ip-prefix font

[LSR3]ip ip-prefix font permit 1.1.1.1 32

[LSR3]ip ip-prefix font permit 4.4.4.4 32

[LSR3]mpls ldp

[LSR3-mpls-ldp]propagate mapping for ip-prefix font

5. 检查配置
