Network Engineering 101- How packet travels through the network
ARP Table : Mapping of IP Address to MAC address Mac Address Table : Mapping of Switchports to Mac Address Routing Table : Mapping of IP Networks to Interfaces Steps 1.) Host A has data for Host D - Host already knows Host D’s IP Address - Host A creates a L3 header - Host A needs to learn Default Gateway’s Mac address 2.) Host A sends an ARP request for 11.11.11.1 3.) Switch X Receives Frame - Switch X learns MAC address Mapping on Port 2 4.) Host B discards frame 5.) Router receives ARP request – Router learns Host A’s ARP mapping 6.) Router generates ARP response 7.) Switch X receives frame - Switch X lea...
