[admin@MikroTik] ip vrrp>
Next the virtual IP address should be added to this VRRP instance
[admin@MikroTik] ip vrrp> address add address=192.168.1.1/24 \
\... virtual-router=vr1
[admin@MikroTik] ip vrrp> address print
Flags: X - disabled, A - active

Now this address should appear in /ip address list:

Configuring Backup VRRP router
Now we will create VRRP instance with lower priority (we can use the default value of 100), so this
router will back up the preferred one:
[admin@MikroTik] ip vrrp> add interface=local
[admin@MikroTik] ip vrrp> print
Flags: X - disabled, I - invalid, M - master, B - backup
0
B name="vr1" interface=local vrid=1 priority=100 interval=1
preemption-mode=yes authentication=none password="" on-backup=""
on-master=""
[admin@MikroTik] ip vrrp>
Now we should add the same virtual address as was added to the master node:
[admin@MikroTik] ip vrrp> address add address=192.168.1.1/24 \
\... virtual-router=vr1
[admin@MikroTik] ip vrrp> address print
Flags: X - disabled, A - active

192.168.1.255

[admin@MikroTik] ip vrrp>
Note that this address will not appear in /ip address list:
[admin@MikroTik] ip address> print
Flags: X - disabled, I - invalid, D - dynamic

Testing fail over
Now, when we will disconnect the master router, the backup one will switch to the master state:
