Joseph,
So if you change the value other than one on K1 for example, then how does
that fit in to the equation? How does eigrp come up with the new metric,
does it multiply the factor lets say bandwidth 2000 and you specify 5=k,
does it mulitply, divide, etc.?
because you can set up to 0-4294967295.
Sincerely,
Matijevic
