Hello Friends...
 
    I am planning to take reverse turn from routing & switching to wan switching, as i my work responsibilities are related more on wan technologies rather than routing or upper layers. I idea or suggestion would be appreciated.
 
    I bought a book for CCNA WAN SW..looks great but bit upset as part II in it gives more hardware or installation details of IGX/BPX/MGX, I expect in exam there will no questions about fans & trays..
 
thanks
rahul.
