A network administrator views the output from the show ip route command. A network that is advertised by both RIP and IGRP appears in the routing table flagged as an IGRP route. Why is the RIP route to this network not used in the routing table?
Answer: B
RIP has an administrative distance (AD) of 120, while IGRP has an administrative distance of 100, so the router will discard any route with a higher AD than 100.

Which of the following statements are true regarding the command ip route 172.16.4.0 255.255.255.0 192.168.4.2?
1.The command is used to establish a static route.
2.The default administrative distance is used.
3.The command is used to configure the default route.
4.The subnet mask for the source address is 255.255.255.0.
Answer: A
Although answer D almost seems right, it is not; the mask is the mask used on the remote network, not the source network. Since there is no number at the end of the static route, it is using the default administrative distance of 1.

You type debug ip rip on your router console and see that 172.16.10.0 is being advertised to you with a metric of 16. What does this mean?
