>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.
