Leo,
One other thing to remember is when using redistribute
connected, I think you'll want to use it on a per-IGP
basis, since I do not think it is transitive (i.e. red
conn for eigrp will not carry over to ospf for
instance). Some one correct me here if I am in error
or fallen into a bad habit.
Now I am accustomed to using route-maps to limit what
I want redistributed and I know that OSPF wants the
subnets keyword and it also likes metrics too and that
EIGRP NEEDS metrics when redistributing between IGPs.
So I would mostly follow the guidelines listed below
unless dictated otherwise by lab requirements.
I may be wrong and become a creature of habit, but I
think like this these days.
Correct me if I am wrong or just too tired at
4:45am...
Here's a reference per univercd:
