COMMENT:
----------------------------------------------------------------------

I found myself wishing that the Abstract and/or Introduction included a
sentence describing what a "covering prefix" was. "ORF" is nicely
explained in the Introduction, but all I get on "covering prefix" is that
they're applicable in Virtual Hub-and-Spoke VPNs and BGP/MPLS Ethernet
VPN networks.

I actually know most of the terms defined in the Terminology section, but
"covering prefix" isn't explained there, either. 

The first clue I could find (searching for "cover") is on page 8, in this
sentence.

   However, because Loc-RIB also
   contains a more specific covering route (3:192.0.2.0/89),
   2:192.0.2.0/88 does not match.  

I can guess what a covering prefix is using context clues, but I'm
guessing.
