We need to restart the quagga service every time if we need to destroy a vlan. This does not happen in freebsd 6.3 and version earlier then 6.3. zebra[3125]: if_ioctl(SIOCGIFFLAGS) failed: Device not configured Just for your information about the step we take to destroy a vlan: 1) remove the subnet from ospfd by using telnet to port 2604 2) ssh into the box and remove the vlan by issue the command ifconfig vlanX destroy When we remove the subnet from ospfd, the system still running fine. However, if we destroy the vlan then only the problem come out. We had just migrated all the routers to freebsd 7.0 and only realize this problem lately. Please don't hesitate to contact me via my email should you need further information from me. Thanks, >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
