Hi all, I've set up keepalived between my 2 Belkin RT1800 (mt7621) routers running OpenWrt 23.05.3. Everything is working very well apart from one thing: VRRP preempting.
I've configured weighted tracking for the WAN interface, so that the backup router should take over with a higher priority, but that isn't happening.
Below is an example instance from my backup router's keepalived.conf.
No matter what settings I change on the luci-app-keepalived (specifically the Disable Preempt option is turned off, but I've tried various other combinations of settings), the nopreempt line never goes away from the configuration.
Both nodes are starting up in backup mode but I've also tried with a primary/backup startup without any difference to preempting.
I'm wondering if I'm missing something or if this could be a bug. Thank you for any pointers.
