Configuring HoVPN
Network requirements
As shown in Figure 56, there are two levels of networks: the backbone and the MPLS VPN networks.
• SPEs act as PEs to allow MPLS VPNs to access the backbone.
• UPEs act as PEs of the MPLS VPNs to allow end users to access the VPNs.
• Performance requirements for the UPEs are lower than those for the SPEs.
• SPEs advertise routes permitted by routing policies to UPEs, permitting CE 1 and CE 3 in VPN 1 to
communicate with each other and forbidding CE 2 and CE 4 in VPN 2 to communicate with each
other.
