Re: [WISPA] OSPF Route Cost Calculations

The problem is I need to know if there is a tool or set of guidelines to determine the proper path cost and priorities in an OSPF network so that when a link goes down the next best route is chosen. On 3/4/2011 8:01 PM, Patrick Shoemaker wrote: This is too general of a question to answer. What

Basically, what is the fastest link in your network? Let's say you have a GigE link. You'll set that cost to 1. Let's say you have a backup link that is a licensed 18GHz link that runs 350 Mbps. You would make that cost a 3. Then, you have a half-duplex Ubiquiti link. Normally you would

Can someone explain, in plain English, the difference between type 1 and type 2 calculations? Mikortik only explains it is white box vs something else. Cisco says A type 1 route has a metric that is the sum of the internal OSPF cost and the external redistributed cost. A type 2 route has a

What is the largest value you can put in for an OSPF cost? I'd almost recommend multiplying all of those numbers by 10 so you can do the fine level tweaking between the links. - Mike Hammett Intelligent Computing Solutions http://www.ics-il.com On 3/5/2011 9:49 AM,

Does any one have a tool or guidelines for setting cost and priority on OSPF interfaces? We had a link go down today. OSPF did what it should, but it did not move to the preferred alternate route. I got it there by changing some costs, but I need a way to get it right without needing a
