[c-nsp] Access-list Question

[Bernd Ueberbacher]

*G* Funny, I had exactly the same problem yesterday! After swearing,
screaming and being sure that it is a bug in IOS, a "?" and exact
reading brought the answer :-)

BUT: Could anyone tell me (or point me to some information) why the hell
there is a wildcard mask? Is there any advantage I don't know or was it
just invented to annoy Paul and me ;-)


Thanks,
Bernd
