By default, the reference bandwidth used in Cisco routers is 100Mbps, so FastEthernet and abovewill 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 beused. 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. Cisco 400-101 Exam "Pass Any Exam. Any Time." - 214

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
