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.
