mpls-vpn实验(H3C)

拓扑：

如图：

R1，R5为ce

R2，R4为pe路由器

R3为p路由器

mpls vpn配置：

①公网igp协议

[R2]int e0/0/1

[R2-Ethernet0/0/1]ip add 23.1.1.2 255.255.255.0

[R2-Ethernet0/0/1]un sh

[R2-Ethernet0/0/1]int loo 0

[R2-LoopBack0]ip add 2.2.2.2 255.255.255.255

[R2-LoopBack0]int e0/0/0

[R2-Ethernet0/0/0]ip add 12.1.1.2 255.255.255.0

[R2-Ethernet0/0/0]un sh

[R3]int loo 0

[R3-LoopBack0]ip add 3.3.3.3 255.255.255.255

[R3-LoopBack0]int e0/0/0

[R3-Ethernet0/0/0]ip add 23.1.1.3 255.255.255.0

[R3-Ethernet0/0/0]un sh

[R3-Ethernet0/0/0]int e0/0/1

[R3-Ethernet0/0/1]ip add 34.1.1.3 255.255.255.0

[R3-Ethernet0/0/1]un sh

[R3-Ethernet0/0/1]q

[R4]int loo 0

[R4-LoopBack0]ip add 4.4.4.4 255.255.255.255

[R4-LoopBack0]q

[R4]int e0/0/0

[R4-Ethernet0/0/0]ip add 34.1.1.4 255.255.255.0

[R4-Ethernet0/0/0]un sh

[R4-Ethernet0/0/0]q

查看ospf neighbor

[R3]dis ospf peer bri

OSPF Process 1 with Router ID 3.3.3.3

Peer Statistic Information

----------------------------------------------------------------------------

Area Id Interface Neighbor id State

0.0.0.0 Ethernet0/0/0 2.2.2.2 Full

0.0.0.0 Ethernet0/0/1 4.4.4.4 Full

----------------------------------------------------------------------------

②启用mpls转发机制和ldp协议

[R2]mpls lsr-id 2.2.2.2 >设定mpls ldp的route-id

[R2]mpls >全局启用mpls转发机制

Info: Mpls starting, OK!

[R2]mpls ldp ####全局启用ldp信令协议

[R2-mpls-ldp]q

[R2]int e0/0/1

[R2-Ethernet0/0/1]mpls ###接口启用mpls

[R2-Ethernet0/0/1]mpls ldp >#接口启用mpls ldp

[R3]mpls lsr-id 3.3.3.3

[R3]mpls

Info: Mpls starting, OK!

[R3-mpls]q

[R3]mpls ldp

[R3-Ethernet0/0/0]mpls

[R3-Ethernet0/0/0]mpls ldp

[R3-Ethernet0/0/0]int e0/0/1

[R3-Ethernet0/0/1]mpls

[R3-Ethernet0/0/1]mpls ldp

[R4]mpls lsr 4.4.4.4

[R4]mpls

Info: Mpls starting, OK!

[R4-mpls]mpls ldp

[R4-mpls-ldp]q

[R4]int e0/0/0

[R4-Ethernet0/0/0]mpls

[R4-Ethernet0/0/0]mpls ldp

③定义vpn-instance和vpn-instance的接口

[R2]ip vpn-instance site1

[R2-vpn-instance-site1]route-distinguisher 1:1 >定义RD

[R2-vpn-instance-site1-af-ipv4]q

[R2-vpn-instance-site1]vpn-target 1:2 export-extcommunity ###定义rt

EVT Assignment result:

Info: VPN-Target assignment is successful.

[R2-vpn-instance-site1]vpn-target 2:1 im

IVT Assignment result:

Info: VPN-Target assignment is successful.

[R2-vpn-instance-site1]q

[R2]int e0/0/0

[R2-Ethernet0/0/0]ip binding vpn-instance site1 ####把接口加入到vpn-instance

[R2-Ethernet0/0/0]ip add 12.1.1.2 255.255.255.0

[R4]ip vpn-instance site2

[R4-vpn-instance-site2]route-distinguisher 2:2

[R4-vpn-instance-site2-af-ipv4]q

[R4-vpn-instance-site2]vpn-target 1:2 import-extcommunity

IVT Assignment result:

Info: VPN-Target assignment is successful.

[R4-vpn-instance-site2]vpn-target 2:1 export

[R4]int e0/0/1

[R4-Ethernet0/0/1]ip binding vpn-instance site2

④启用pe-ce路由协议

CE配置

[R1]ospf 1 rou 1.1.1.1

[R1-ospf-1]area 0

[R1-ospf-1-area-0.0.0.0]net 10.1.1.0 0.0.0.255

[R1-ospf-1-area-0.0.0.0]net 1.1.1.1 0.0.0.0

[R1-ospf-1-area-0.0.0.0]net 12.1.1.1 0.0.0.0

[R5]ospf 1 rou 5.5.5.5

[R5-ospf-1]area 0

[R5-ospf-1-area-0.0.0.0]net 5.5.5.5 0.0.0.0

[R5-ospf-1-area-0.0.0.0]net 45.1.1.0 0.0.0.255

[R5-ospf-1-area-0.0.0.0]net 10.1.2.0 0.0.0.255

PE配置

[R2]ospf 2 vpn site1

[R2-ospf-2]area 0

[R2-ospf-2-area-0.0.0.0]net 12.1.1.2 0.0.0.0

[R2-ospf-2-area-0.0.0.0]q

[R4]ospf 2 vpn-instance site2

[R4-ospf-2]area 0

[R4-ospf-2-area-0.0.0.0]net 45.1.1.4 0.0.0.0
