Refer to the exhibit.

An engineer needs to configure a floating static route for an external EIGRP network. The destination subnet is the /29 on the LAN interface of R86.

Which command must be executed on R14?

  • A ip route 10.80.65.0 255.255.248.0 10.73.65.66 1
  • B ip route 10.80.65.0 255.255.255.240 fa0/1 89
  • C ip route 10.80.65.0 255.255.255.248 10.73.65.66 171
  • D ip route 10.73.65.66 0.0.0.224 10.80.65.0 255
Explanation

A floating static route must have an administrative distance higher than the dynamically learned route so it is used only as a backup. EIGRP external routes have administrative distance 170, so the static route must be set above that, such as 171. The target network is R86’s LAN subnet 10.80.65.0/29, and from R14 the correct next hop toward that subnet is 10.73.65.66. That yields ip route 10.80.65.0 255.255.255.248 10.73.65.66 171.
