Configure EBGP between the Spoke-CEs and Spoke-PEs and between the 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. Configure MP-IBGP between the Spoke-PEs and Hub-PE to exchange VPN routing
information.
