>Release: FreeBSD 3.3-STABLE i386
>Organization:
>Environment:
Multicast-enabled network interface(MNI) has multiple IP addresses.
Gated started from rc.network script.
>Description:
Message 'multicast not available; reverting to RIP V1 version' appears
on system console during boot. This problem disappears, if you restart
gated after boot.
>How-To-Repeat:
Just boot system with router='gated' in /etc/rc.conf.
>Fix:
This problem caused by missing syslogd daemon. Error reporting function
changes actual errno and make gated believe that MNI doesn't have multicast.
Here is a hack to fix this.
