Easy 6in4 (proto-41) tunneling:

Thus you are using one /64 but are splitting it over 2 interfaces? :)
And you are also putting the complete 2002::/16 on the sitl interface.
You might want to change that to a /64 and use another /64 for the
other interface. If you say 'but the 2002::/16 is there' why don't
you simply put a netmask of 0 or 3 in it then? For adding routes use
the route command, not the netmask option. The /48 contains 65535 /64's
thus you might just want to use more than one of them.
Oh and please put a note below it that using the anycast 6to4
address _will_ cause high latency and low bandwidth issues when
trying to reach non-6to4 sites unless you are very happy to have
a local 6to4 anycast relay of which there are only a few in the
world. Basically boiling down to the fact that if you really
want to get started with IPv6 and start using it, try to convince
your own ISP or a nearby one to provide you connectivity or
ofcourse use any of the local tunnelbrokers. The note should be
there otherwise people will 'try' 6to4 and complain that IPv6
sucks because it is slow while the real reason is that they
are located in the US and are using a anycast 6to4 relay in europe...
Next to that if you want a reverse DNS delegation for 6to4
you have to contact hostmaster@ep.net, note that this is
for ip6.int, for ip6.arpa there are no reverses, yet and
probably never will be.
