Hello Ty,
I apologize if I offended you. I wasnt saying that you didnt do any
research, I was just making a general observation.
Again, my sincere apologies, this is a great forum, with very good
engineers, we can all try and make this a better place. I hope you find the
article I provided you as well to be helpful.
Sincerely,
Matijevic

before posting a question, when I don't fully understand something from the
documentation. I did research, before I posted the question. We all learn
from asking questions. If the purpose of the forum is to not ask questions
and learn about something we don't understand, then I will refrain from
doing so. However, as I stated before, I am fully aware of doing a search,
which I have already done. That is why the question was posted. My very
first search was actually done on the DOC CD under eigrp. I did not fiind
anything on the DOC CD that under eigrp that even stated anything about
variance. It wasn't my last search however. By your response, you are
stating that I did not do that, without even asking me first. Once again,
the only reason I posted the question was to try to get more understanding
about it. I didn't post the question looking for an easy way out. aA few
people responded...it gave me bet!
