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.
Cisco routers do send RA by default as soon as IPv6 is enabled on the interface.
- 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.
Linux (at least Debian/Ubuntu kernels) will accept RAs by default even if you set a static IPv6 address. To stop it you have to do: sysctl net.ipv6.conf.eth0.accept_ra=0 -- Mikael Abrahamsson email: swmike@swm.pp.se
