Open Issues (1) Comparison with MIPv6: Related experiences with MIPv6 and its approach to the identity / locator split and the differences between this and the approaches proposed with multi-homing. The aspect of MIPv6 which appears to present issues in the context of multi-homing is the return routeability mechanism. In MIPv6 identity validity is periodically tested by return routeability of the identity address. This use of a distinguished locator as the identity token cannot support return reachability in the multi-homing context in the event of path failure. |
