I am only interessted about the logic. We are planing to do BGP-4, and
now I read realy accurate the rfc2622 (RPSL) and found this filter

{^20-24}^26-28} == {^26-28}

But why should I do like the first block? What is the advantage from the
first? I can not figure out whats the difference, or is it just the
same. So if anyone can give me a tip would be great.

Thanks for your help
