Configuring a hub-spoke network

Network requirements
The Spoke-CEs cannot communicate directly. They can communicate only through Hub-CE.
Configure EBGP between the Spoke-CEs and Spoke-PEs and between Hub-CE and Hub-PE to
exchange VPN routing information.
Configure OSPF between the Spoke-PEs and Hub-PE to implement communication between the
PEs, and configure MP-IBGP between them to exchange VPN routing information.
