World of Computer Networking Your CCNA start - End-to-End Internet Protocol (IP) Packet Transmission - Part 2

The video tutorial explains the process of packet forwarding in a network. It begins with the router receiving a packet at its Gigabit 0/0 interface, performing decapsulation, and checking the routing table to determine the next hop. The router sends an ARP request to resolve the MAC address of the destination host. After receiving the MAC address, the router decrements the TTL, updates the header checksum, and encapsulates the packet with a new Ethernet header. Finally, the router transmits the Ethernet frame through the appropriate interface.
