A network administrator is configuring a Cisco router to forward all traffic destined for the internet through a specific next-hop IP address. Which type of route should the administrator configure?
- ASummary route
- BHost route
- CNetwork route
- DDefault route
Show answer & explanationAnswer & explanation
Correct answer: D. Default route
A default route is used to forward packets for which there is no specific entry in the routing table. This is essential for connecting to the internet or other networks with unknown destinations.
Why the other options are wrong
- A. A summary route consolidates multiple specific routes into a single, broader route.
- B. A host route specifies a path to a single, specific host IP address.
- C. A network route specifies a path to an entire network segment.
Default Route
A default route is a special type of static route that specifies the gateway to use when a router cannot find a path to a destination in its routing table.
- Represented as 0.0.0.0/0 in IPv4 or ::/0 in IPv6.
- Acts as a 'last resort' route.
- Essential for internet connectivity.
Memory trick: Route types direct traffic, but one is the 'go-to' for the unknown.
