Exercise :: IP Routing - IP Routing

  • IP Routing - IP Routing

Which of the following statements are true regarding the command ip route

  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

A. 1 and 2
B. 2 and 4
C. 3 and 4
D. All of the above

Answer: Option 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.


Which command displays RIP routing updates?

A. show ip route
B. debug ip rip
C. show protocols
D. debug ip route

Answer: Option B


The debug ip rip command is used to show the Internet Protocol (IP) Routing Information Protocol (RIP) updates being sent and received on the router.


Which statement is true regarding classless routing protocols?

  1. The use of discontiguous networks is not allowed.
  2. The use of variable length subnet masks is permitted.
  3. RIPv1 is a classless routing protocol.
  4. IGRP supports classless routing within the same autonomous system.
  5. RIPv2 supports classless routing.

A. 1, 3 and 5
B. 3 and 4
C. 2 and 5
D. None of the above

Answer: Option C


Classful routing means that all hosts in the internetwork use the same mask. Classless routing means that you can use Variable Length Subnet Masks (VLSMs) and can also support discontiguous networking.


You have the following routing table. Which of the following networks will not be placed in the neighbor routing table?

R [120/1] via, 00:00:12, Serial0
C is directly connected, Serial0 is subnetted, 1 subnets
C is directly connected, Loopback0
R [120/1] via, 00:00:12, Serial0
R [120/15] via, 00:00:07, Serial0
C is directly connected, Ethernet0

D. All of them will be placed in the neighbor routing table.

Answer: Option C


The network cannot be placed in the next router's routing table because it already is at 15 hops. One more hop would make the route 16 hops, and that is not valid in RIP networking.


What is split horizon?

A. Information about a route should not be sent back in the direction from which the original update came.
B. It splits the traffic when you have a large bus (horizon) physical network.
C. It holds the regular updates from broadcasting to a downed link.
D. It prevents regular update messages from reinstating a route that has gone down.

Answer: Option A


A split horizon will not advertise a route back to the same router it learned the route from.
