>Description:
In order to use IPv6 autoconfiguration (i.e., rtsol) as well as additional
IPv6 addresses for an interface (for virtual hosting), I put the following
in /etc/rc.conf:
ipv6_enable="YES"
ipv6_ifconfig_fxp0_alias0="3ffe:0507:018b:0001:d1dc:f7bc:0000:0001"
Since there is no "ipv6_ifconfig_fxp0" setting, the interface will be
autoconfigured. However, /etc/rc.network6 (in network6_interface_setup())
adds alias entries before calling rtsol. rtsol doesn't autoconfigure
the the interface address if it already has one.
>How-To-Repeat:
>Fix:
I believe the rtsol must be done before the alias processing. I've tested
this in my setup and it works.
