[c-nsp] BGP subnet mask display

[Ashe Canvar]

Thanks Guys. 
An update from my side. I found this great tool called ipcalc (perl script) :

basically I do :

for x in `cat ./PREFIXLIST`; 
do 
./ipcalc.pl -n -b  $x | grep Network | awk '{print $2}'; 
done >> PREFIXES-NORMALIZED

Gives me a "corrected" list with netmasks.

The other thing is that quagga/zebra can provide "classless" table
dumps. Cisco still sucks though. :)

Cheers.
