 This option registers a :doc:`status monitor </development/backend/carp>` on top of the FRR logging feed to detect changes in link status,
 when OSPF can't find its neighbors it will make this machine less attractive by increasing the demotion factor.

 FRR natively does not support interaction with carp status as the variant in openbsd does
 (carp note in “depend on” keyword https://man.openbsd.org/ospfd.conf.5), this is where our next option comes into play.
 
 Using the interface settings of an OSPF interface you can choose to adjust costs for that interface based on the carp status of the
-selected virtual address. Go to :menuselection:`Routing --> OSPF -> Interface` and choose an interface, here you will find the
+selected virtual address. Go to :menuselection:`Routing --> OSPF[v3] -> Interface` and choose an interface, here you will find the
 following options that influence behaviour:
