</P>
<P><FONT SIZE=2 FACE="Arial">Pavlin and I have been discussing what the "right" direction should be for the network4 operator in policy statements. Right now if you specify "network4 <= 10.0.0.0/8" this would match all the 10.0.0.0/8 and longer prefixes (i.e. 10.0.0.0/9, 10.1.0.0/16, etc.).</FONT></P>
<P><FONT SIZE=2 FACE="Arial">My recommendation is to change the operator from "<=" matches longer prefixes to ">=" matches longer prefixes, since this seems more intuitive to me (/9 is > /8) and this would make it match the "prefix-length4" operator where "prefix-length4 > 24" matches all prefixes longer than /24.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Which do you prefer:</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">A) keep it the way it is now, < matches longer prefixes</FONT>
<BR><FONT SIZE=2 FACE="Arial">B) changing it to use > for longer prefix matches</FONT>

<P><FONT SIZE=2 FACE="Arial">Btw, the bug on this is 358</FONT>
