A router has used the OSPF protocol to learn a route to the 172.16.32.0/19 network. Which command will implement a backup floating static route to this network?
- ip route 172.16.0.0 255.255.240.0 S0/0/0 200
- ip route 172.16.32.0 255.255.224.0 S0/0/0 200
- ip route 172.16.0.0 255.255.224.0 S0/0/0 100
- ip route 172.16.32.0 255.255.0.0 S0/0/0 100
Answers Explanation & Hints:
OSPF has an administrative distance of 110, so the floating static route must have an administrative distance higher than 110. Because the target network is 172.16.32.0/19, that static route must use the network 172.16.32.0 and a netmask of 255.255.224.0.
