Re: Cisco One Article

Software won't take away the need to know QoS and other CCIE level topics.I
would be surprised to see the foundation of everything under the
application layer disappear because a more powerful decision is making
routing decisions. I see your point about HA. V Motion across the world and
router lives every where. I think it's pretty cool but won't stop me from
pursuing CCIE.
