Refer to the exhibit. An engineer is attempting to have 192.168.32.100 forwarded through 10.1.1.1, but it was forwarded through 10.1.1.2. What action forwards the packets through 10.1.1.1?

  • A Configure EIGRP to receive 192.168.32.0 route with lower metric.
  • B Configure EIGRP to receive 192.168.32.0 route with lower admin distance.
  • C Configure EIGRP to receive 192.168.32.0 route with longer prefix than /19.
  • D Configure EIGRP to receive 192.168.32.0 route with equal or longer prefix than /24.
Explanation

Forwarding uses the longest matching prefix, so the existing RIP /24 route is selected over the EIGRP /19 route for 192.168.32.100. An EIGRP route with an equal /24 prefix is preferred over RIP because EIGRP has the lower administrative distance (90 versus 120); a longer matching EIGRP prefix also takes precedence by longest-prefix match.
