| Summary | 0000351: IPv6 only network on bond lacp interface | ||||
| Description | Hello, We have discovered a strange bug related to IPv6-only machines. Just default Almalinux-8 installation (in my case it was 8.6 but upgrade to 8.7 makes no difference) We have two network interfaces and we like to have bond interface using LACP. Key point: it is ipv6-only network, so ipv4 address is not exist in the configuration, only ipv6 address After installation, networkmanager is constantly hanging (disabling slaves, then bond, then try to enable it again, and so on). Its fully working btw, once it get it up - network is working perfectly but then NetworkManager "detect" something wrong and disabling slaves and bond itself. Reproduced on multiple machines, seems not related to network drivers and specific network card. Easy fix: just add dummy IPv4 to config with /32 prefix without gateway fix the issue and LACP are keeping to be up. | ||||
| Steps To Reproduce | * Install AL-8 with two network interfaces, creating bond interface on top of it with mode 802.3ad * Use only IPv6 address on bond0 interface * NetworkManager getting it up and down all the time | ||||
