The primary function of a network is to provide connectivity between devices.
Packet Routing
Packets must be routed when two devices are on different networks. As the data is encapsulated with its IP address, a device detects that its destination is on a different network and must be routed.
The device checks the local routing table to identify its next-hop IP address.
Aim is to ping from R1 <-> R2 and understand the end to end logic
