Example for Configuring HoVPN
Network requirements
There are two levels of networks, the backbone and the MPLS VPN networks, as shown in Figure
6-25 .
z
SPEs act as PEs to allow MPLS VPNs to access the backbone.
z
UPEs act as PEs of the MPLS VPNs to allow end users to access the VPNs.
z
Performance requirements for the UPEs are lower than those for the SPEs.
z
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.
