[PE]ospf 1

[PE-ospf-1]area 0

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

[PE-ospf-1-area-0.0.0.0]network 30.1.1.0 0.0.0.255

3. 在骨干网上配置MPLS基本能力和MPLS LDP，建立LDP LSP

[UPE]mpls lsr-id 1.1.1.1

[UPE]mpls

[UPE]mpls ldp

[UPE-GigabitEthernet0/0/0]mpls

[UPE-GigabitEthernet0/0/0]mpls ldp

[SPE]mpls lsr-id 2.2.2.2

[SPE]mpls

[SPE]mpls ldp

[SPE-GigabitEthernet0/0/0]mpls

[SPE-GigabitEthernet0/0/0]mpls ldp

[SPE-GigabitEthernet0/0/1]mpls

[SPE-GigabitEthernet0/0/1]mpls ldp

[PE]mpls lsr-id 3.3.3.3

[PE]mpls

[PE]mpls ldp

[PE-GigabitEthernet0/0/0]mpls

[PE-GigabitEthernet0/0/0]mpls ldp

4. 配置UPE与SPE、PE与SPE的MP-IBGP对等体关系

[UPE]bgp 100

[UPE-bgp]peer 2.2.2.2 as-number 100

[UPE-bgp]peer 2.2.2.2 connect-interface LoopBack 0

[UPE-bgp]ipv4-family vpnv4

[UPE-bgp-af-vpnv4]peer 2.2.2.2 enable

[SPE]bgp 100

[SPE-bgp]peer 1.1.1.1 as-number 100

[SPE-bgp]peer 1.1.1.1 connect-interface LoopBack 0

[SPE-bgp]peer 3.3.3.3 as-number 100

[SPE-bgp]peer 3.3.3.3 connect-interface LoopBack 0

[SPE-bgp]ipv4-family vpnv4

[SPE-bgp-af-vpnv4]peer 1.1.1.1 enable

[SPE-bgp-af-vpnv4]peer 3.3.3.3 enable

[PE]bgp 100

[PE-bgp]peer 2.2.2.2 as-number 100

[PE-bgp]peer 2.2.2.2 connect-interface LoopBack 0

[PE-bgp]ipv4-family vpnv4

[PE-bgp-af-vpnv4]peer 2.2.2.2 enable

5. UPE和PE上创建VPN实例，并与CE间配置EBGP

[UPE]ip vpn-instance vpna

[UPE-vpn-instance-vpna]ipv4-family

[UPE-vpn-instance-vpna-af-ipv4]route-distinguisher 100:1

[UPE-vpn-instance-vpna-af-ipv4]vpn-target 1:1

[UPE-GigabitEthernet0/0/1]ip binding vpn-instance vpna

[UPE-GigabitEthernet0/0/1]ip add 10.1.1.1 24

[UPE]bgp 100

[UPE-bgp]ipv4-family vpn-instance vpna

[UPE-bgp-vpna]peer 10.1.1.4 as-number 65410

[UPE-bgp-vpna]import-route direct

[CE1]bgp 65410

[CE1-bgp]peer 10.1.1.1 as-number 100

[CE1-bgp]import-route direct

[PE]ip vpn-instance vpna

[PE-vpn-instance-vpna]ipv

[PE-vpn-instance-vpna]ipv4-family

[PE-vpn-instance-vpna-af-ipv4]route-distinguisher 100:2

[PE-vpn-instance-vpna-af-ipv4]vpn-target 1:1

[PE-GigabitEthernet0/0/1]ip binding vpn-instance vpna

[PE-GigabitEthernet0/0/1]ip add 10.2.1.3 24

[PE]bgp 100

[PE-bgp]ipv4-family vpn-instance vpna

[PE-bgp-vpna]peer 10.2.1.5 as-number 65420

[PE-bgp-vpna]import-route direct

[CE2]bgp 65420

[CE2-bgp]peer 10.2.1.3 as-number 100

[CE2-bgp]import-route direct

6. SPE上配置路由反射器

[SPE]bgp 100

[SPE-bgp]ipv4-family vpnv4

[SPE-bgp-af-vpnv4]undo policy vpn-target

[SPE-bgp-af-vpnv4]peer 1.1.1.1 reflect-client

[SPE-bgp-af-vpnv4]peer 1.1.1.1 next-hop-local
