(usagi-users 00488) Routing question

[Wang Kai <wangkai1@xxxxxxxxxxxxxxx>]

Dear all,
I want to ask you a question on IPv6 routing.
Now I have a small network configured with private
addresses(10.0.0.0/24). In this network, I divided it into two
subnets(10.0.1.0/24 and 10.0.2.0/24)  connected with a router. Before I
enable IPv6, two subnets can communicate with each other. Since each
node in the network has a private IPv4 address, now I configured each
node with an IPv4-compatible address constructed from each node's
private IPv4 address. So earh node now has an IPv6 address, for example,
::10.0.1.1/120 and :10.0.2.1/120. For enabling a node to talk with nodes
in the other subnet, I have to configure each node's IPv6 routing table
to add an entry for the other subnet. Now it works! As for why I use
IPv4-compatible address, this is just one experiment in
our testbed. Since IPv6 has the function of stateless autoconfiguration
and I have installed router advertisement daemon(radvd) in the router.
Is there any way to configure this router to let it advertise its
reachability to each subnet automatically? I have to try to configured
radvd many times, but it always failed! I check RFC2462 and RFC2461, it
says that IPv6 prefix advertisement is only for construting IPv6
address. So it can't advertise the prefix longer that 64-bit. Is there
any way to make it automatically?
I don't know whether I have expressed my question clearly.
Thanks in advance!
