Yes, create a plan. As I understand, you get routed 2001:328:2003::/48
to you.

Now start subnetting.

E.g.
2001:328:2003:0000::/56 -> for directy to the tunnel endpoint connected
networks like
	2001:328:2003:0001::/64 eth0
	2001:328:2003:0002::/64 eth1
	...

2001:328:2003:0100::/56 -> for subnets on internal IPv6 island router 1
2001:328:2003:0200::/56 -> for subnets on internal IPv6 island router 2

Then you create static tunnels between the tunnel endpoints (at least a
star, but you can also setup a mesh).

And now setup proper routes, e.g. on border tunnel:

2001:328:2003:0100::/56 dev sit2
where tunnel sit2 points to 192.168.202.1

For the first, use tcpdump on source and destination and look, whether
it is a forward (no ICMP packets are received on destination) or a
backward routing (answers never received by source) problem.
