From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: The system loosing an ipv6 address/route distributed via autoconf after the lifetime. this worked with fedora core 2. Interestingly when I start tcpdump, I see the Router Advertisements, and the it starts working. Not using tcpdump once => not working. I suppose this has something to do with the acceping/receiving of multicast frames. Version-Release number of selected component (if applicable): kernel-2.6.9-1.667 How reproducible: Always Steps to Reproduce: 1. Boot the box 2. IPv6 address there 3. Wait for the address lifetime 4. address gone Expected Results: The Lifetime timers should be updated every time a new RA is received Additional info:
It seem to be cured by setting the device into promiscous mode for a sufficently long period of time (longer than the ra-interval is enough): ifconfig $DEVICE promisc && sleep $INT && ifconfig $DEVICE -promisc
