ISATAP tunneling in the UE is not for inter-IP-domain.
There can be one or more L2 networks between the UE the ISATAP box
but the UE and ISATAP box would always be in the same IP domain.
Maybe this was a comment in reference to 3gpp roaming? If so I want
to point out that it is L2 roaming (not L3 roaming). So there is no
crossing of IP domain.
