Question:
Which type of route will require a router to perform a recursive lookup?

  • an ultimate route that is using a next hop IP address on a router that is not using CEF
  • a level 2 child route that is using an exit interface on a router that is not using CEF
  • a level 1 network route that is using a next hop IP address on a router that is using CEF
  • a parent route on a router that is using CEF

Explanation: When Cisco Express Forwarding (CEF) is not being used on a router, a recursive lookup must be performed when a route using a next-hop IP address is selected as the best pathway to forward data.​
