The core switches will be 2 x HP ProCurve 6200yl (Core A and Core B), each with the 10GB module (ProCurve Switch yl 10-GbE 2-Port CX4 + 2-Port X2 Module)installed for stacking.
Edge switches will be HP ProCurve 2824. (Edge A, Edge B, Edge n)
Connection between the core and access layer switch will be via Fibre, using "ProCurve Gigabit-SX-LC Mini-GBIC".
To ensure connectivity and max up time at the core switch level, each of the edge switch will have 2 connections back to the core switches, 1 to Core A and 1 to Core B.
Correct me if I am wrong.
Understand the switches will use "Spanning Tree" protocol to prevent loopback, as there is a close connection: Edge A -> Fiber cable -> Core A -> CX4 cable -> Core B -> Fiber cable -> Edge A.
Is "Spanning Tree" by default turned on at the switches?
Lets say Core A is down, all the paths are re-direct to Core B, if Core A is up again, those paths using Core A will auto re-direct back to Core B? Or need to re-direct back manually?
Please assist.
Thanks.
Solved! Go to Solution.

SolutionYour imagination is 100% correct.
Core1-Core2

EdgeA
Before you Physically connect above drawing, make sure:
1- Turn on Spanning Tree on all the Switches.
2- Run on CoreA:
CoreA(config)#span prio 0
* this will make sure that CoreA is the Root*
3- Run on CoreB:
CoreB(config)#span prio 1
* this will make sure that CoreA is the backup*
After yo udo this, connect all the switches like in the drawing (Each edge has 2 links, one to Corea and one to CoreB)
NOW all the links to CoreB with be blocked by Spanning Tree.
And if CoreA is down, all the Links to CoreB will be acive in less than 200ms.
Now if CoreA is back, all the links to CoreB will be blocked again.
Good Luck !!!
