--- Comment #15 from Kurt Jaeger <pi@FreeBSD.org> ---
(In reply to Marek Zarychta from comment #14)
man ifconfig says:

-L Display address lifetime for IPv6 addresses as time offset
             string.

but it does not change the output from ifconfig.

ndp still shows that link-local adresses have a very strange behaviour when=
 it
comes to lifetimes. It changes from 24 hours to less than 60 seconds in a v=
ery
quick step. Why ?

c5$ ndp -an | grep 1270
fe80::1270:fdff:fe66:7d18%vlan500    10:70:fd:66:7d:18 vlan500 23h59m56s S R
fe80::1270:fdff:fe66:e721%vlan500    10:70:fd:66:e7:21 vlan500 11s       R R
c5$ ndp -an | grep 1270

c5$ ndp -an | grep 1270
