Yes you can change the cost that way too...in this case though you can't get better than 1 which is why it is changed on the backup link.
I am not 100 percent on this but I think the sham link gets a cost of 3 or something pretty small. I would need to look that up Sent from my Verizon Wireless BlackBerry Regards, Joe Astorino - CCIE #24347 Sr. Technical Instructor - IPexpert Mailto: [email protected] Telephone: +1.810.326.1444 Live Assistance, Please visit: www.ipexpert.com/chat eFax: +1.810.454.0130 IPexpert is a premier provider of Self-Study Workbooks, Video on Demand, Audio Tools, Online Hardware Rental and Classroom Training for the Cisco CCIE (R&S, Voice, Security & Service Provider) certification(s) with training locations throughout the United States, Europe, South Asia and Australia.

However, I have one question regarding the manipulation of costs. I know that the cost on the backup link was at a minimum of one, however if we were to manipulate the cost in such a way that the better cost would be define in the area X sham-link cost statement; would there be any functional differences? Also, with the absense of the cost value in the area X sham-link, how exactly is the cost derived for the sham-links? Thanks again for the video. Regards, Nasser.
