Hi,
Just for clarification, the 25% is not the amount for the unclassified. It's
the reserved part for hellos, keepalives, routing updates, Integated
Services signaling and other specific traffic from the routers inner
processes. And the 25% reserve for that can be used by other traffic as long
as the legitime owners (the stated processes) don't use them.
The class default doesn't have any guaranteed bandwidth at all by default,
unless you use the "bandwidth percent %" or "bandwidth Kbps" in the default
class configuration
Just follow my previous post.
Regards
Daniel
