R1, R2, and R3 have full network connectivity to each other, but R2 prefers the path through R3 to reach network 172.17.1.0/24. Which two actions can you take so that R2 prefers the path through R1 to reach 172.17.1.0/24? (Choose two.)

  • A. Set the reference bandwidth to 10000 on R1, R2, and R3.
  • B. Configure the cost on the link between R1 and R3 to be greater than 100 Mbps.
  • C. Set the reference bandwidth on R2 only.
  • D. Configure a manual bandwidth statement with a value of 1 Gbps on the link between R1 and R3.
  • E. Modify the cost on the link between R1 and R2 to be greater than 10 Gbps.
  • F. Configure a manual bandwidth statement with a value of 100 Mbps on the link between R1 and R2.

Suggested Answer: AB 🗳️
By default, the reference bandwidth used in Cisco routers is 100Mbps, so FastEthernet and above will have a cost of 1, so a gigabit interface and 10GE interface will be equal with a fastethernet. This is not ideal. If we change the reference bandwidth to 100000 then the faster links will be used. Changing the reference bandwidth needs to be done on all routers in the OSPF network. Increasing the cost on the R1-R3 link will also cause the traffic to take the more direct route.
