Refer to the exhibit.
Which two statements are correct? (Choose two.)
A.
This is a default route.
B.
Adding the subnet mask is optional for the ip route command.
C.
This will allow any host on the 172.16.1.0 network to reach all known destinations beyond
RouterA.
D.
This command is incorrect, it needs to specify the interface, such as s0/0/0 rather than an IP
address.
E.
The same command needs to be entered on RouterA so that hosts on the 172.16.1.0 network
can reach network 10.0.0.0.
Default gateway is usually used on switches that are not L3 switches/routers or on “hosts”. It just points to a router that “knows” how to get out.
The term “Default Route” usually means “ip route 0.0.0.0 0.0.0.0 x.x.x.x” or “default-information originate”. And means, if you don’t have a “more specific” route, then send it to x.x.x.x, and that router will take care of it.
“Default-information originate”, is the exact same thing as “ip route”, except it’s sending it through a routing protocol.
If a router learns a default route from another router through a routing process, it will have a cost associated, as well as the administrative distance of the routing protocol. The important information is the AD (administrative distance). When we type the command “ip route” the AD for that route is 1 (unless we change it). If we learn a default route from OSPF, it will have the AD of OSPF (110). So the static will be preferred.
hat is the use of default route?
A default route of a computer that is participating in computer networking is the packet forwarding rule (route) taking effect when no other route can be determined for a given Internet Protocol (IP) destination address. All packets for destinations not established in the routing table are sent via the default route.
