VRRP Backup Always Becomes Master

RouterOS General
1

We have setup VRRP between two locations with a Ubiquiti wireless link in between. The problem is that the backup router always becomes master after about 30 seconds. Backup router is 5.14 and the master is 5.12 but the backup side started at 4.5 and upgrades didn’t fix the problem. Once the backup becomes master, it never switches back.

Master

/interface vrrp
add arp=enabled authentication=none disabled=no interface=bridge1 interval=1s \
    mtu=1500 name=vrrp1 on-backup="" on-master="" password="" preemption-mode=\
    yes priority=254 v3-protocol=ipv4 version=3 vrid=65

Backup

/interface vrrp
add arp=enabled authentication=none disabled=yes interface=bridge1 interval=1s \
    mtu=1500 name=vrrp1 on-backup="" on-master="" password="" preemption-mode=\
    yes priority=100 v3-protocol=ipv4 version=3 vrid=65

The VRRP IP is a /32 and each router has an IP on the same /27 that the /32 sits on.

Any ideas as to why the backup always becomes master?

r u able to ping each other LAN IPs from each other Router. Generally when preempt mode is yes. Then it makes running VRRP as master.

Most likely the problem is ubiquity wireless link not able to pass multicast packets properly. Connect VRRP routers directly and then see if VRRP works.
