So, I'd want a separate CVE for the general BGP design issue. > or are you talking about another BGP issue? (but in the same "family" > as CVE-2009-2055 and CVE-2010-3035). I can't quite tell the difference between CVE-2009-2055 and what Florian is requesting a CVE for. In CVE-2009-2055, Cisco seems to be implying that it's a problem in XR, not the design of the whole protocol - but it's not immediately clear if they even "fixed" it. The issue at hand is whether we need a new CVE or a rewrite for the old CVE-2009-2055. - Steve
