Configuring a hub-spoke network
Network requirements
• The spoke-CEs are not permitted to communicate with each other directly. Data transmission
between them depends on the hub-CE.
• Configure eBGP to exchange VPN routing information between spoke-CE and spoke-PE, and
between hub-CE and hub-PE.
• Configure OSPF between spoke-PE and hub-PE to ensure IP connectivity between PEs, and
configure MP-iBGP to exchange VPN routing information.
