While optimal routing is not a requirement, I'd venture to say that pure
reachability is!

Hi Brian,
Thank you very much for your response, but do i have to insure full
reachability even for example for routes received from the BB routers, and
prevent all kind of routing loops, even if i am not asked to, what is scope
of full reahability.
BR,
Mohammed Mahmoud.

Subject: Re: Mutual redistribution and loop prevention Do whatever you need
to ensure full reachability. If a routing loop is causing you to not have
full reachability then resolve it.

Hi everybody,
I heard a lot about over thinking tasks in the exam, and i've a small
question to know if i am over thinking this issue or not, it is regarding
mutual redistribution and loop prevention.
Lets assume that i was asked to do a lot of mutual redistributions, which
eventually will cause routing loops, and after wards i was asked to prevent
certain routing loops at certain points in the network, does this mean that
i don't have to prevent all routing loops at all points in the network, just
the loops i was asked to prevent, or do i have to prevent all routing loops
in the topology, which is sometimes cumbersome.

Mohammed Mahmoud.
