VRRP preempt mode with LACP and older devices
There can be an issue with VRRP preempt mode if an older device is the intermediate device connecting to a VRRP router and has LACP set in "enable, passive" mode. This mode is set by default on older devices, whereas it is disabled by default on later models. It is recommended that you use compatible LACP settings on devices that connect with VRRP routers on VRRP VLANs.
