Anyone know how we can configure a tunnel IPv6 between a Link Service(4) in JUNOS [6.0R1.5] and a FreeBSD 4.8 box?
Any pointer would be appreciated.

JUNOS Configuration:

gr-0/1/0 {
traceoptions {
flag all;
}
unit 0 {
tunnel {
source 200.160.0.130;
destination 200.160.0.9;
}
family inet6 {
address 2001:12ff::1/126;
}
}
}

ge-1/3/0 {
description "GE gw02 <-> gw01 (iBGP)";
speed 1g;
link-mode full-duplex;
unit 0 {
family inet {
no-redirects;
address 200.160.0.130/30;
}
}
}

FreeBSD Interfaces Configuration:

$ ifconfig em1
em1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=3<rxcsum,txcsum>
inet 200.160.0.9 netmask 0xffffffc0 broadcast 200.160.0.63
inet6 fe80::20b:dbff:fe90:ea73%em1 prefixlen 64 scopeid 0x2
ether 00:0b:db:90:ea:73
media: Ethernet 100baseTX <full-duplex>
status: active

$ ifconfig gif0
gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
tunnel inet 200.160.0.9 --> 200.160.0.137
inet6 2001:12ff::2 prefixlen 64
inet6 fe80::20b:dbff:fe90:ea72%gif0 prefixlen 64 scopeid 0x7

Sorry for this information. The correct gif0 Configuration is:

gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
tunnel inet 200.160.0.9 --> 200.160.0.130
-------------
inet6 2001:12ff::2 prefixlen 64
inet6 fe80::20b:dbff:fe90:ea72%gif0 prefixlen 64 scopeid 0x7
