John!!
A million apologies.....!!
Nowhere have I said that this book is useless .... :-)
My post said Clarification - that's it !!
All I wanted is clarification - if I do this will my points get deducted
and same for if I don't do this.
Have done most if not all the InternetworkExpert Labs and having gone
thru the Brian's training, I was only trying to get my self prepared for
the actual Lab....
Anyone else's comments - please feel free?
Anyone concur - especially the ones from InetExp's forums - ??
Sincerely.

As far as the eigrp >process, you could use the passive interface default

160.10.0.0/24 network. >You could have also just put the interface in the
