I'm still not clear on what role max-reserved-bandwidth plays in
protecting the routing protocol traffic.
Isn't 25% of interface bandwidth reserved for control plane traffic by default?
If so do you really need a separate class to reserve bandwidth for
routing traffic?
Or is that only necessary if you set max-reserved-bandwidth to 100%?
Thanks again for your replies.
