Abstract:
In one embodiment, a method includes generating by a mobile router a home test message that includes a prefix option field specifying at least one mobile network prefix claimed to be owned by the mobile router. The method also includes outputting the home test message by the mobile router to a correspondent node via a prescribed home agent assigned to the mobile router, for initiation of a reverse routability test between the mobile router and the correspondent node that verifies the mobile router owns the at least one mobile network prefix. In another embodiment, the home agent is configured for forwarding a route optimization message, for example the home test message, to the correspondent node if the home agent determines that the at least one mobile network prefix is owned by the mobile router.
