    Question they would want to choose an ISR over an ASA

    Hi,

    Below sentence is referred from this link "cisco.com". I am not sure the meaning of "over" in the following sentence.
    Note: ISR and ASA are two different products from Cisco.

    So for example if a customer wants to run BGP to a provider they would want to choose an ISR over an ASA. Or if a customer wants to do some URL filtering they would choose an ASA and not an ISR.
    For the highlighted sentence, does it mean A or B?:
    A. they would want to choose an ISR, and they won't choose an ASA.
    B. they would want to choose an ISR in addition to an ASA (choose both ISR and ASA).

    I found a definition for "over and above" from Longman dictionary which may relate to the meaning of the above "over", but I not sure:
    over and above: in addition to something

    Please help to explain, thanks.

    I would ask Cisco. The sentence could mean either. On first reading I understood over to mean "in preference to".

    Re: they would want to choose an ISR over an ASA

    So, which is correct now? I prefer to B on first reading, but guess to A after reading remaining sentence (Or if a customer wants to do some URL filtering they would choose an ASA and not an ISR).

    I would say A, for sure. The word over means in preference to or instead of.

    Only Cisco can tell you which is correct. The writer would have meant that both devices are required if an ISR requires an ASA to run "over" (that is, in conjunction with). Otherwise, they meant that an ISR is a better choice than an ASA.
