[nsp] Prefix 0.0.0.0/1

[Sonny I Franslay]

Hi Robert,

IOS ver 12.0(10)S. I've tried both commands but no effect. I believe it's
the way cisco router treats prefix 0.0.0.0 irregardless of the prefixe
length (whether /0 or /1).
Am I right? Was hoping someone could enlighten me on this.

Many thanks and Merry Xmas to everyone..
