OSPF not working on RouterOS v7.1 between 2 routers

Tue Dec 07, 2021 8:52 am

Hello,

I have just upgraded to Router OS V7.1 on 2 of my routers and everything seems to work perfectly normal with the exception of OSPF.
OSPF works without any issues in Router OS v6.49.2 but I can't get it working in v7.1
I have attached the 2 router configs. For now I can only provide the configs as I have reverted back to v6.49.2. I can do testing only outside business hours.

HQ-Router
/routing ospf instance
add disabled=yes name=default-v3 version=3
add name=default-v2
/routing ospf interface-template
add area=backbone-v2 interfaces="Vlan10-LAN" networks=10.1.10.0/24/24
add area=backbone-v2 interfaces="Vlan88-VMs" networks=10.1.88.0/24
add area=backbone-v2 interfaces="Vlan90-Management" networks=10.1.90.0/24
add area=backbone-v2 interfaces="Vlan110-WorkVPN" networks=10.1.110.0/24
add area=backbone-v2 interfaces="Vlan120-PulseVPN" networks=10.1.120.0/24
add area=backbone-v2 interfaces=GRE-Branch-RDS-RDS networks=172.22.22.0/30 type=ptp
/routing ospf area
add instance=default-v2 name=backbone-v2
add disabled=yes instance=default-v3 name=backbone-v3
Branch-Router
/routing ospf instance
add disabled=yes name=default-v3 version=3
add name=default-v2
/routing ospf interface-template
add area=backbone-v2 interfaces="LAN Bridge" networks=192.168.100.0/24
add area=backbone-v2 interfaces=GRE-HQ-RDS-RDS networks=172.22.22.0/30 type=ptp
/routing ospf area
add instance=default-v2 name=backbone-v2
add disabled=yes instance=default-v3 name=backbone-v3
Am I doing something wrong or am I missing something ?
The idea is that the routers are seeing each other (OSPF wise), but they are always stuck on neighbor state = ExStart and they are not getting past that point.

ExStart state; in most cases is if different MTU is on the link between routers.
Is there anything in the log?

looks like firewall rule is required:
/ip firewall filter
add action=accept chain=input in-interface=<change_me> protocol=ospf

Not just you having an issue with OSPF on v7. I was unable to run it over a tunnel where v6 worked fine before so I had to revert the upgrade. Hope these things are fixed soon
