How to set static IPv6 address/gateway in Arch (NOT tunnel)

Question

Hey Everybody,
Today I decided to install Arch Linux. There was only one thing that I did not understand, and that is how to set up a static IPv6 address. I have native IPv6 connectivity at home and in Debian I used to edit /etc/network/interfaces to set up a static IPv6 adress. Since Arch uses rc.conf, what is the syntax to configure a static IPv6 address?
I used to add something like this in Debian in /etc/network/interfaces:
> iface eth0 inet6 static
> address *my static address*
> netmask 64
> gateway *my gateway address*
Or can I still use /etc/network/interfaces in Arch?
Thank you for help.

It can be done quite easily using the netcfg infrastructure.
/usr/lib/network/connections/ipv6static
#!/bin/bash
. /usr/lib/network/network
ipv6static_up() {
load_profile $1
ip -6 a a ${ADDRESS} dev ${INTERFACE}
if ! [ -z "${GATEWAY}" ]
then
ip -6 r a 2000::/3 via ${GATEWAY} dev ${INTERFACE}
fi
ipv6static_down() {
load_profile $1
ip -6 a d ${ADDRESS} dev ${INTERFACE}
if ! [ -z "${GATEWAY}" ]
then
ip -6 r d 2000::/3 via ${GATEWAY} dev ${INTERFACE}
fi
ipv6static_$1 $2
exit $?
/etc/network.d/eth0static
CONNECTION="ipv6static"
DESCRIPTION="Static configuration for IPv6"
ADDRESS="2001:dead:beef:cafe::1/64"
INTERFACE="eth0"
GATEWAY="2001:feed:dead:beef::1" # Comment this out if no route needed
I haven't tested the gateway part, but I don't see why it wouldn't work. You'll need iproute2, and to read up on netcfg (see http://wiki.archlinux.org/index.php/Network_Profiles) if you have trouble.
