           Summary: routes disappear with 'could not determine nexthop' log
                    entry
           Product: Quagga
           Version: CVS
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: Very High
         Component: ospfd
        AssignedTo: maintainers at quagga.net
        ReportedBy: windo at p6drad-teel.net


I have a test setup with two openvpn tunnels between two routers. I have been
testing to see if I can failover from one link to another in a suitable time and
ran into a possible bug.

It happens when I fail block one link, wait for quagga to apply the route
through the other link (with higher cost), failback to the original tunnel, wait
for around 5-10 minutes and block the original tunnel again. Now, this time
ospfd logs:

OSPF: ospf_nexthop_calculation(): could not determine nexthop for link

and removes all routes about 5 seconds (5 seconds is my hello timer interval)
before dead timer reaches 0. After that, routes through the other failover link
(the one with the higher cost) are brought up.
