I had an Interface disappear from config due to bouncing. Was physical cable issue. But that is resolved. I was getting some overruns and errors on TX side. I replaced cable and resolved issue. But the interface was missing from config mode. Non-config mode it was there. Very weird. Anyways I had to manually add it back and setup the interface again. But when I tried to add the IPv6 address I am getting this issue. I already rebooted and that doesn’t help. Any help is appreciated.
After trying out some stuff with dmbaturin on the IRC and it seems my problem was some syntax validation problem which was fixed but it required me to remove VPN config and reapply it agian before i could do “show config commands” and get expected results.
I still however have my problem where the config for my WAN dissappears but it has been narrowed down the the DHCP and DHCPv6 rewrites and the IPv6 validation. Cause if i dont use DHCPv6 in my config, my VyOS box will remember the WAN config.
