Cisco CCNA (200-301)IP ConnectivityMedium
A network technician is configuring a Cisco router to forward traffic for network 192.168.50.0/24. They issue the command `ip route 192.168.50.0 255.255.255.0 10.0.0.2`. What type of static route is this?
- ARecursive static route
- BDefault static route
- CDirectly connected static route
- DFloating static route
Show answer & explanationAnswer & explanation
Correct answer: A. Recursive static route
This is a recursive static route because the next-hop IP address (10.0.0.2) is not directly connected to the router. The router must perform a lookup in its routing table to find out how to reach 10.0.0.2 before it can forward packets to 192.168.50.0/24. This recursive lookup makes it a recursive static route.
Why the other options are wrong
- B. A default static route uses 0.0.0.0 0.0.0.0 as the destination network.
- C. A directly connected static route specifies a directly connected exit interface, not a non-local next-hop IP.
- D. A floating static route has a higher administrative distance than the primary route, providing a backup path, which is not indicated here.
Recursive Static Route
A static route where the next-hop IP address is not directly connected to the router, requiring the router to perform an additional lookup to find the path to the next-hop.
- Next-hop is an IP address not on a directly connected network.
- Requires the router's routing table to have a route to the next-hop IP.
- Can fail if the route to the next-hop IP is lost.
Memory trick: Direct is near, Recursive needs a guide, Default is wide, Floating is a backup ride.
