That one. IPv6 routes almost always use LL addresses. My srt0 config
(from /etc/ifconfig.srt0) is ...
!srtconfig srt0 add 2001:3c8:9009:181::2 /64 xennet0 fe80::1
!srtconfig srt0 add 2001:3c8:9007:1::21 /64 xennet1 fe80::9007:1:1
!srtconfig srt0 add 0::0 /0 xennet0 fe80::1
!route -q add -inet6 default fe80::1%srt0
Note that I don't care (nor does anything else) that srt's are nominally
p2p interfaces (that is, I don't bother setting a meaningless destination
| Hm, that's odd; I'm not seeing a v6 LL address on my srt0,
If you don't assign it one, none will appear. But you also (on -5)
might be running an if_srt version old enough that v6 didn't work properly
at all. That was fixed ages ago, but I'm not sure how many ages.
