said by cramer:Cisco has actually shown running demos of vIOS (L2, L3) and vNX-OS.
the ccie r/s exam is done completely with iol and l2-iol.
the new blueprint of the ccie s/p will all be virtualized as well.
this has pros and cons -- as with the movement towards "hardware agnostic" virtualized platforms -- comes a removal of a lot of the idiosyncrasies around hardware (think things like cat-qos). on the other hand -- the emphasis is placed on difficulty of the topics that can be thrown at you -- as well as on things like tshoot, etc.
that being said -- my experience with titanium has been complete shit -- even when instantiated through cml. things like xr-v, csr1000v, and the ios-v -- work well (to some degree) though caveats exist (especially on the xr-v platform) due to the removal of some of the functionality done through the npu and lpts complex on the asr9k that has yet to be virtualized into the software.
