>Description:
rtadvd just doesn't work - i mean don't broadcast packets.
when stopped,started and in between (when it have to send packet) it says in
logs:
 rtadvd[68836]: <ra_output> sendmsg on em0: Network is down

network isn't down!

system is uptime for 40 days serving all services through em0 for local users over IPv4.

IPv6 works and is configured - but just rtadvd doesn't

tcpdump shows rtadvd doesn't send any packets


rtadvd DOES WORK on my other systems.

problem is interface (only here i have em interface) or something else dependent.


ifconfig em0:
em0: flags=88843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,STATICARP> mtu 1500
        options=4b<RXCSUM,TXCSUM,VLAN_MTU,POLLING>
        inet6 fe80::21b:21ff:fe00:9e16%em0 prefixlen 64 duplicated scopeid 0x1 
        inet 10.254.1.248 netmask 0xfffffc00 broadcast 10.254.3.255
        inet 10.254.1.232 netmask 0xfffffc00 broadcast 10.254.3.255
        inet6 2001:4070:101:1::2 prefixlen 64 
        inet6 2001:4070:101:1::3 prefixlen 64 
        inet6 2001:4070:101:1::4 prefixlen 64 
        ether 00:1b:21:00:9e:16
        media: Ethernet autoselect (1000baseTX <full-duplex>)
        status: active



>How-To-Repeat:
add
rtadvd_enable="YES"
rtadvd_interfaces="em0"

and /etc/rc.d/rtadvd start


>Fix:
NO IDEA! please give me a hint i need rtadvd running
