CE 1 accesses the network through PE 1 in AS 100 andCE 2 accesses the network through PE 2 in AS 200.z Inter-provider MPLS L3VPN is implemented using option A. That is, the VRF-to-VRF method isused to manage VPN routes.z The MPLS backbone in each AS runs OSPF.Figure 1-20 Configure inter-provider VPN option ALoop0 Loop0Loop0 Loop0Vlan-int11CE 1 CE 2AS 65001 AS 65002PE 1 PE 2ASBR-PE 2ASBR-PE 1MPLS backbone MPLS backboneAS 100 AS 200Vlan-int11 Vlan-int11Vlan-int11Vlan-int12Vlan-int12Vlan-int13Vlan-int13Vlan-int12Vlan-int12Device Interface IP address Device Interface IP addressCE 1 Vlan-int11 10.1.1.1/24 CE 2 Vlan-int11 10.2.1.1/24PE 1 Loop0 1.1.1.9/32 PE 2 Loop0 4.4.4.9/32Vlan-int11 10.1.1.2/24 Vlan-int11 10.2.1.2/24Vlan-int12 172.1.1.2/24 Vlan-int12 162.1.1.2/24ASBR-PE 1 Loop0 2.2.2.9/32 ASBR-PE 2 Loop0 3.3.3.9/32Vlan-int12 172.1.1.1/24 Vlan-int12 162.1.1.1/24Vlan-int13 192.1.1.1/24 Vlan-int13 192.1.1.2/24Configuration procedure1) Configure IGP on the MPLS backbone, implementing the connectivity in the backboneThis example uses OSPF.
