PERFECTION

Fun Time - First Look

Last Night I  was fully toasted after doing almost 14 Hrs of  Labbing and Readings. As the lab is approaching I can feel the heat around now. To get rid of this I had a beer and went through some old CCIE funny stuff I remember and no doubt it made me laugh again. Specially the Scott Morris Jokes :-) ... Will add more links here after lab.

BTW... If you don't know who is Scott Morris and assume yourself as a CCIE Candidate, without any delay shoot yourself  :-)

Benefit of adding Phase 3 Configuration allows us to reduce control-plane information on Hub Router. Also it allows us to use default routing and perform summarization on Hub.
