Supposing, we have following pieces in a theoretical network architecture
- Network A: A low power IPV6 wireless network
- Some low power hosts: Low power devices which are connected to the above low power IPV6 wireless network.
- Network B: a Wi-Fi Network
- A border Router which is connected to a Wi-Fi AP and also part of the low power IPV6 wireless network.
- Some Wi-Fi stations: which are connected to the same Wi-Fi AP, to which border router is connected.
Considering above architecture, The border router enables bi-directional IP connectivity between these two different networks. In such setup, when a host in Wi-Fi network wants to reach to one of the hosts in the Lowe power IPV6 network, what will be sequence of packet flow?
For example, the 'Host x' in Wi-Fi network wants to send a packet to 'Host x1' in low power ipv6 network, will following be the packet sequence?
Host x -> Wi-Fi AP -> Border Router -> Host x1 .
Is above correct? if yes, How Wi-Fi AP knows which device it should forward the packet to? or how does it it know that, it should forward the packet which is destined for 'Host x1' to the Border router only? Which information's are required by the Wi-Fi AP to know before hand for getting this to work?
Or if the sequence of packet flow is incorrect, please suggest what will be the correct flow or sequence of packet transmission.
