    - Routing is the decision over which interface a packet is to be sent. This decision has to be made for locally created packets.

    - Routing table contain network addresses and the associated interface.

    - Forwarding is a decision of the system. It refers to packet which reach a system but are not destined for this system.

    - Routing tables are stored in RAM.

    - Forwarding tables on high-performance gear will be distributed across line cards and stored in higher-speed TCAM.

    - Router means finding a suitable path for a packet from sender to destination and forwarding is the process of sending the packet toward the destination based on routing.
