On the back of a recent support case it turns out there is no current option to change the OSPF router ID using InControl.
Once the Route Advertisement is managed by InControl there is no way to set a custom OSPF Router ID. It would also be handy to have the option to use a different VLAN’s IP Address as the OSPF router ID as currently the Untagged LAN is the default OSPF router ID. In our use case we don’t use the Untagged LAN as we use the same VLAN number across different devices (Peplink, Cisco, Etc) for ease of use
@Arthur_Gladwin thanks for working with us on the case.
I believe the case has been resolved and the feature (changing OSPF Router ID) has been implemented in InControl 2, and it shall be included in the upcoming version of the ICVA firmware (current version is 2.13.1.2).
