Hello GS
  What is the best way to spot or identify routing loops? Is there
something that can readily ID routing loops? What are some of the
things that could cause routing loops
All inputs, links comments are welcome

Thanks for all inputs

Not by what I'd seen of the lower certs for DC. *shrug* Security,

Storage is different from data center, i thought data center was combo
of Voice, R&S, security and storage.
