|
|
Term
| first step in the routing process |
|
Definition
| router receives a data packet and reads the IP address of it destination |
|
|
Term
| second step in the routing process |
|
Definition
| router consults its routing table to find the quickest route to the destination IP address |
|
|
Term
| Third step in the routing process |
|
Definition
| router replaces the media access control address given as the packet destination with the mac address of the next hop |
|
