I know that is how Cisco figures default values, but it is not always the best. I may have a 10M wire link and a 54M wireless link. The average data flow is 5M, so want the 10M wire to be the primary because it is more reliable. I would give it a lower cost than the faster wireless link.

If you have a wireless link that you know suffers from temperature inversion problems every morning and one that doesn't, but is slower, you may want the slower, more reliable link to have the lower cost so that your reliability stays high, but if that link goes down, you still have a link to use.

As with most things in this business, there are general guidelines, but you also have to know your network and make informed decisions, not just follow some rule of thumb.

Cost should be set based on the speed of the link. So, if you have a 1 Gbps link in your network, set the cost of routers on either side to 1. If you have a 333 Mbps link, set the cost of the routers on either side to 3. 100 Mbps link? Cost = 10. So, your 1 Gbps link speed is really 1000 Mbps so cost = 1000 / Speed.

        I have a network with about 800 devices running OSPF.  If you
        need more help, let me know.
        I do consulting for several WISPs helping get from bridged to
        routed, setting up routers correctly, etc.
        If is is easy, no charge.  If is going to take some
        time/effort, I charge $65.00/hour for the actual time
        involved, no minimum.  Let me know what I can do to help.
