>Description:
I have rtadvd running to provide IPV6 configuration for the internal network, which uses interface em0.
/etc/rc.conf contains:
ifconfig_em0="inet 192.168.0.12 netmask 255.255.255.0"
ifconfig_em0_ipv6="auto_linklocal 2001:xxx:yyyy:zzz::1 prefixlen 64"
rtadvd_enable="YES"
rtadvd_interfaces="em0"
The server is also running mpd5 to provide PPTP vpn services.
When a PPTP vpn disconnects, the corresponding netgraph (ng) interface is destroyed.
When this happens, rtadvd generates a syslog error in /var/log/messages:
Mar 24 08:52:23 mail rtadvd[35606]: <rm_ifinfo_index>: ifinfo not found (idx=12)
This error should not be logged, since rtadvd is not listening no or servicing any netgraph interfaces.
>How-To-Repeat:
Configure an interface with ipv6 and configure rtadvd on this interface.
Install and configure mpd5.
Start rtadvd and mpd5
Establish a VPN and disconnect the VPN.
Error message is loged everytime a VPN disconnects.
