Example for Configuring HoVPN

Network requirements
There are two levels of networks, the backbone and the MPLS VPN networks, as shown in
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 the 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.
