ppl say that USA is more stable
BTW: is possible to have 2 tunels on 1 system? for example i will make new interface he-ipv6-2 and tunel to frankfurt?
I would disagree with the statemant that usa tserver are more stable. The fra has more then 2000 tunnels. The only issue that I have noticed is the reloading of the tserver - vary rare (once a few weeks) but happens.
It's possible to have more then one tunnel. Howevere isn't so simple as you expect. A routed /64 is assigned to the tunnel. So you wan't be able to push it throught the secend tunnel.
