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
