Hi,

You can run v4 and v6 in parallel on a single link, or you can run
v6 over v4 from your upstream provider - if they can do that.

For example, we get upstream connectivity from AS1273 (C&W), and our
uplink interface is configured like this:

interface GigabitEthernet2/6
 description Uplink GE to Cable&Wireless 1273
 ip address xx.yy.255.162 255.255.255.252
 ip access-group 110 in
 ip flow ingress
 ip pim bsr-border
 ip pim sparse-mode
 ip multicast boundary 60
 ipv6 address 2001:xx:xx:17::2/64

-> voila, very straightforward.

Definitely.

Still, it doesn't make any sense to throw a tunnel from us to Pakistan,
as I'm sure that there are other v4+v6 enabled networks closer to you.

As you mention *Pakistan*, you might want to check the archives of the
ipv6-ops mailing list, http://lists.cluenet.de/pipermail/ipv6-ops, as
we just had two people from Pakistan resolving IPv6 issues on the 
list - just yesterday.  Subject was "Tunnel & BGP peering".

(This is getting off-topic for c-nsp anyway - and I can only recommend
the ipv6-ops list to everyone interested in IPv6 operational content.
Low volume, highly targeted content).
