interesting. I am not seeing that. Using your static LL routes: # ip -6 ro ls ::1 dev lo proto kernel metric 256 pref medium 2001:db8:2::/120 dev eth2 proto kernel metric 256 pref medium fe80::5:73ff:fea0:52d dev eth4 metric 100 pref medium fe80::/64 dev eth4 proto kernel metric 256 pref medium fe80::/64 dev eth5 proto kernel metric 256 pref medium fe80::/64 dev eth6 proto kernel metric 256 pref medium fe80::/64 dev eth7 proto kernel metric 256 pref medium fe80::/64 dev eth8 proto kernel metric 256 pref medium fe80::/64 dev eth2 proto kernel metric 256 pref medium default via fe80::5:73ff:fea0:52d dev eth4 metric 100 pref medium can you send me the network config files (off list is fine)? What's the interface manager and any routing daemon in use?
