This does not seem to be generally true: - For the routers I am most familiar with (Juniper M/MX), you need to explicitly turn on router advertisement to make the router perform this. I.e. it is perfectly possible to have an interface with an IPv6 address which does *not* send RAs. - For the operating system I am most familiar with (FreeBSD), RAs are *not* accepted by default if the interface in question is configured with a static IPv6 address. Both of these choices seem perfectly reasonable to me. Steinar Haug, Nethelp consulting, sth...@nethelp.no
