Please ay comment about the first question? Port startup time is a cisco
definition term, I don't know what does it mean exactly.

1. What about max age time? The minimum max age is 6 seconds.
Minimum forward delay is 4 seconds.

So 6+(4*2) = 14 seconds is the minimum, isn't it?

Someone please verify these numbers...

2. If you only have one point of redistribution you should not need any
loop avoidance mechanisms. If you have two or more points of
redistribution you may need tags or tweak administrative distance
depending on the scenario.
