3.18 Configuration Examples
This section provides several configuration examples of VPN networking. In each configuration
example, the networking requirements, configuration roadmap, configuration notes,
configuration procedures, and configuration files are described.
3.18.1 Example for Configuring BGP/MPLS IP VPN
This section describes how to configure the basic BGP/MPLS IP VPN, which involves the
configurations of MPLS LSPs, VPNv4 peers, and VPN instances.
Networking Requirements
As shown in Figure 3-2:
l CE1 and CE3 are in VPN-A.
l CE2 and CE4 are in VPN-B.
l The VPN target attribute of VPN-A is 111:1, and that of VPN-B is 222:2.
l Users in different VPN cannot access each other.
