hi,
i don't see anything bad with your config, currently i'm using
something quite similar:
/etc/hostname.xl0:
inet 10.0.0.4 255.255.255.0 NONE
inet6 alias 2001:x:4da3::1
/etc/hostname.tun0:
!/usr/sbin/ppp -ddial -unit0 myisp
/etc/ppp/ppp.conf:
default:
set log tun phase
myisp:
set log phase
set redial 15 0
set device "!/usr/sbin/pppoe -i ep1"
set speed sync
set authname mylogin
set authkey mypasswd
set mtu max 1492
set mru max 1492
disable mssfixup acfcomp protocomp
deny acfcomp protocomp
enable lqr
/etc/ppp/ppp.linkup:
myisp:
add! MYADDR 127.0.0.1
add! default HISADDR
add! MYADDR6 ::1
add! default HISADDR6

afaik yes; that's what ifconfig(8) gives for my tun(4) device:
$ ifconfig tun0
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1492
groups: tun egress
inet6 fe80::2e0:29ff:fe00:2e0d%tun0 -> prefixlen 64 scopeid 0x8
inet x.x.x.x --> y.y.y.y netmask 0xffffffff

hmm.. this may overwrite your local-link address. Try to make an
alias with your statc IPv6 address:
ifconfig tun0 inet6 alias 2001:x:3000:1
