IPv6 default route is lost

  • Hello,

    I’m using 2.4.3-RELEASE-p1 on comcast. The problem I’m having is that after a few minutes/hours after release/renew or reboot IPv6 stops working. On investigation, I see that there is no IPv6 default route, which is consistent with IPv6 no longer working. Both WAN and LAN interfaces still have their IPv6 addresses, only the default route is missing. What I don’t understand is why the default route is lost after initially working.

    As a workaround I have disabled IPv6. This is unfortunate however unreliability over such a short timescale is unacceptable and renders the connection near unusable.

    This appeared to start happening after I upgraded to 2.4.3-RELEASE-p1. I believe I was previously on a 2.3.x version so it’s a pretty big jump in versions so unfortunately this doesn’t really narrow down when the bug was introduced.

    Has anyone else hit this problem?

    No, it’s solid here.
