Hi Tim,

I want to dissuade you from using this architecture. When you have two
paths, it's important to keep them both lit so that you can detect
faults and correct them in a timely manner. The most intractable
problem with active/failover architectures is that the failover proves
inoperable when it's needed. The old backup tape that doesn't restore.
Keep your layer-1's active all the time and do fault handling at a
higher layer.
