[c-nsp] full duplex mismatch speed - dynamips

[Jeferson Guardia]

 Guys,

Thanks for all replies, googling it I came across a link at groupstudy from
someone experiencing the same problem before when labbing up CCIE
topologies.

I think it is a dynamips 'bug/weird behavior' , the way of getting rid of
this issue is only disabling CDP, if anyone knows another way out, please
let me know.
