Re: [RRG] Separation vs. Elimination

[Michael Menth <menth@informatik.uni-wuerzburg.de>]

Hi Dan,

I read the paper and liked it. Very clear and to the point!

Just one comment. The terms "separation" and "elimination" do not really 
correspond to each other as the first term points to the solution and 
the second term to a result. Elimination of longer prefixes from BGP 
routing tables by multi-homed end nodes corresponds to hiding these 
prefixes by routing separation. I hope this makes clear what I mean.

Best regards,

Michael
