I had this very same question a few weeks ago and was advised that using the
"max-reserved-bandwidth 100" is probably not the best idea, unless you are
explicitly told to. The reasons being that it is entirely possible that
during times of congestion you can end up dropping routing protocol and
control traffic, which would effectively cripple your network.
