Network requirements
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 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 from communicating
with each other.
