Can anyone help me explain 3 type of VPN routing for example "To center and to other satellites through center" I have to add Center GW and two satellites gateways to the same vpn community? 


  • To center only. No VPN routing actually occurs. Only connections between the satellite gateways and central gateway go through the VPN tunnel. Other connections are routed in the normal way
  • To center and to other satellites through center. Use VPN routing for connection between satellites. Every packet passing from a satellite gateway to another satellite gateway is routed through the central gateway. Connection between satellite gateways and gateways that do not belong to the community are routed in the normal way.
  • To center, or through the center to other satellites, to internet and other VPN targets. Use VPN routing for every connection a satellite gateway handles. Packets sent by a satellite gateway pass through the VPN tunnel to the central gateway before being routed to the destination address.
