The router reads all the lines and then determines the proper route.
|
|
|
What is the purpose of the default route in a routing table?
|
The default route tells the router where to send every packet unless another line in the routing table gives another route.

|
|
|
What do routers do when there is more than one path to a destination network?
|
The lowest metric is always the most preferred by routers.
|
|
|
Why are link state protocols more efficient than distance vector routing protocols?
|
Link state protocols forward only changes to individual routes whereas distance vector protocols forward entire routing tables.
|
|
|
Which of the following is a hybrid dynamic routing protocol because it can be used as both an IGP and an EGP?
