If you left the AdvValidLifetime option in radvd to default 
(i.e. infinity) then it shouldn't expire. I haven't gotten as
far as that in the code but with a quick look the prefix
processing code in addrconf_prefix_rcv() seems to do
just that.

And new router advertisement must not invalidate old
information unless they refer to the same prefix, mtu
etc.
