A Possible New Solution A Down-link multicast connection E.g. for Router Advertisements All MSs may join this well-known multicast connection Router advertise the prefixes with L-bit reset No neighbors except the ARs Routers proxy for the end nodes (MSs) for Address Autoconfiguration Setup a default connection between MS and BS that can be used for IP Signaling Requires only the implementation change for Routers No Protocol changes are required MS IPv6 Stack can support multiple interfaces e.g. 802.11, 802.16 |
