(5) in my original post automatically change the VRRP priority when I unplug the cable from the public interface.
The results are posted as in the original post – when MT local interface is in backup mode, the interface can ONLY communicate via VRRP with the Cisco router. No one, even the Cisco router, can ping it.
When the VRRP is enabled on the MT local interface or the VRRP role is changed on the MT local interface, one of the static route, 10.0.0.0/8 via 10.23.0.3, becomes invlaid even it remains in the routing table which can be seen by /ip route print
Please help.
