[c-nsp] BGP conditional advertisement

[Ahmed Hilmy]

Hi Friends,

when i force prefix Z to be advertised to ISP A only and to ISP B only when
ISP A is down.
does my end customer will face an outage or a flap ?  i want that the
recovery time should be fast enough that the customer will not be able to
sense it.
Does  conditional advertisement do that ?
