RFC 1933 doesn't seem to talk about any mechanism for actually
establishing the IPv6o4 tunnel - are there any standards describing how to
authenticate the creation of such a thing? A statically configured tunnel
is fine, but when one of the endpoints is dynamic there needs to be some
way for the mobile end to authenticate himself and bring the tunnel back
up.

Presumably, IPSEC AH should be used on the outer encapsulating packets to
avoid e.g. another modem user in the dialup pool hijacking the tunnel
after a user disconnects, but that still doesn't specify the handshake
mechanism. Any suggestions?
