I believe you use a deprecated (~10 years ago ?) way to setup your
tunnel, its not a linux-3.0 new behavior.
sit0 is reserved (fall back tunnel), you should use a different name.
Try :
# ip tunnel add aster mode sit local 216.111.203.89 remote 209.51.18.1 ttl 255
# ifconfig aster up
# ip tunnel
sit0: ipv6/ip remote any local any ttl 64 nopmtudisc
aster: ipv6/ip remote 209.51.18.1 local 216.111.203.89 ttl 255
