Fresh Build Not Taking IPv6 RA's?

[Thomas Donnelly]

Hi,

I have a few servers on a vlan which have all happily auto configured 
via RA, both FreeBSD and CentOS boxes. However, I freshly installed a 
FreeBSD 7 box, brought it to stable, and it wont auto configure.

I'm kind of at a loss at what could be the issue. Anyone have ideas on 
where to start?

Thanks

so it is hearing the RA
