We upgraded our routers to lasest OS version FW version: RUT9XX_R_00.06.08.3.
CPU load is less than 30%.
Now we faced a new issue - when IPSec phase 1 and 2 is rekeying (lifetime set to 8 hours for both phases), we lose traffic exchange for 3 - 4 minutes.
And when WAN link is "down", IPSec tunnel stay in "up" state.
Any suggestons ?
