Hello.
My back bone presently has a port cost of 2, which connects our two core switches.
The rest of my link currently have a port cost of 4.
The network is set up in such a way that each stack of switches has a link to both core switches.
Now if my backbone with a current cost of 2 was to fail, which of the parths with a port cost of 4 would spanning tree decided to use? The one with the least hops? Everything with a port cost of 4 is connected by gigabit fibre, so the only varible i can see is the amount of hops/switches.
Many thanks.
Mike.
