FRR OSPF6 Router-ID configuration statement has changed
Trying out the latest 2.4.5 RC and I noticed that my ospf6 router-id had reverted to the default of picking the highest IP address on the box.
Looking at the FRR docs the router-id statement has changed from router-id A.B.C.D to ospf6 router-id A.B.C.D.
Not sure when this was changed but it now lines up with the OSPFv2 configuration so it does make sense. Should be quick fix i've tested changing line 131 and 133 in frr_ospf6.inc and it works as expected.
