1. On the backbone network, configure VPN instances on the PEs connected to CEs and bind
related VPNs to the interfaces connected to the CEs. Then, assign IP addresses to the
interfaces connected to the CEs.
2. Configure OSPF between the PEs to implement interworking between PEs.
3. Configure basic MPLS functions and MPLS LDP and create MPLS LSPs.
4. Configure MP-IBGP for exchanging VPN routing information.
5. Configure EBGP between the CE and the PE to exchange VPN routing information.
6. Configure the Dot1q sub-interface to access the L3VPN on the interface connecting the PE
and CE.
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 5-16
l IP addresses of VLANIF interfaces, as shown in Figure 5-16
l MPLS LSR-IDs of PEs and P
l RDs of VPN-A and VPN-B
l VPN targets of received and sent routes of VPN-A and VPN-B
l Encapsulation mode and VLAN ID of the sub-interface
Procedure
Step 1 Configure an IGP on the MPLS backbone network so that the PE and P can interwork with each
other.
