Re: EIGRP - Split Horizon

Jules,

Apology accepted and I, in turn, offer an apology to you as well for
any shortness I may have displayed throughout the course of this
rather long discussion. We must be a couple of hard-core geeks to be
carrying on about EIGRP in such a way! ;-)

I respect your passion and you have certainly helped to exercise my
understanding - and perhaps lack thereof in some cases - of what I
regard to be a pretty cool protocol. I may perform some additional
lab testing tomorrow and if I do, I'll post additional CLI output and
packet capture. Nah, scratch that! Enough of EIGRP for me for a
while...

Cheers sir,

Scott
