Description of problem: I have a network where two devices are sending router advertisements (SLAAC): the actual edge router (AdvHomeAgentFlag off; AdvDefaultPreference medium) and a MIPv6 home agent (AdvHomeAgentFlag on; AdvDefaultPreference low). If I boot kernel 4.1.6-200.fc22.x86_64 or earlier, the edge router is selected and used as the default outbound route. If 4.1.6-201.fc22.x86_64 or later is used (currently latest is 4.1.8-200), home agent is selected as the default route. Version-Release number of selected component (if applicable): kernel 4.1.6-201.fc22.x86_64 or later. How reproducible: 100% Steps to Reproduce: 1.boot selected kernel and login 2.wait until NetworkManager establishes the connection 3.see "ip -6 r sh" Actual results: Default router is fe80::21d:72ff:... Expected results: default via fe80::21d:70ff:... dev wls1 proto static metric 600 Additional info:
As usual, reproducibility disappeared after pressing submit. Closing this bug for further investigation...
