The route flush does that, I'm not sure how you can instruct it to 
ignore some set of addresses, without explicitly deleting every address 
*but* the IPv6 link-local addresses. Ifconfig isn't involved here, but 
using an awk script to parse the output of route -n show and strip all 
lines starting with fe80: (and nondata), followed by a print $1 then an 
xargs route delete would work, wouldn't it?
