CE3 GigabitEthernet1/0/0 VLANIF 40 10.3.1.1/24
CE4 GigabitEthernet1/0/0 VLANIF 50 10.4.1.1/24
Configuration Roadmap
The configuration roadmap is as follows:
1. Configure VPN instances on the PEs connected to CEs on the backbone network and bind
related VPNs to the interfaces connected to the CEs.
2. Configure OSPF on the PEs and P to implement interconnection between PEs.
3. Configure the basic MPLS capabilities and LDP and create an MPLS LSP.
4. Configure MP-IBGP for exchanging routing information between the VPNs.
5. Configure EBGP for exchanging VPN routing information between the CE and PE.
Data Preparation
To complete the configuration, you need the following data:
l IDs of the VLANs that the interfaces belong to, as shown in Figure 3-3
l IP address of each VLAN interface, as shown in Figure 3-3
l MPLS LSR-IDs of PE and P
l RDs of vpna and vpnb
l VPN targets of received and sent routes of vpna and vpnb
Procedure
Step 1 Configure IGP on the MPLS backbone network so that PEs and P can interwork.
