I have a topology like this:

enter image description here

this Router0-1's Gig0/0/0 ip: 10.0.12.1/24, the Router0-2's Gig0/0/0 ip: 10.0.12.2/24, Gig0/0/1 ip: 10.0.23.2/24, this Router0-3's Gig0/0/0 ip: 10.0.23.3/24,

at first, all the router interfaces are announced into the Area 0.

now, I announced the Router0-3's Gig0/0/0 and Router0-2's Gig0/0/1 to the Area1, but the Router0-2 get bellow logs:

00:57:06: %OSPF-4-ERRRCV: Received invalid packet: mismatch area ID, from backbone area must be virtual-link but not found from 10.0.23.2, GigabitEthernet0/0/1

00:57:16: %OSPF-4-ERRRCV: Received invalid packet: mismatch area ID, from backbone area must be virtual-link but not found from 10.0.23.2, GigabitEthernet0/0/1

00:57:26: %OSPF-4-ERRRCV: Received invalid packet: mismatch area ID, from backbone area must be virtual-link but not found from 10.0.23.2, GigabitEthernet0/0/1

00:57:36: %OSPF-4-ERRRCV: Received invalid packet: mismatch area ID, from backbone area must be virtual-link but not found from 10.0.23.2, GigabitEthernet0/0/1

....

I have tried clear ospf prgress in Router0-3, still this issue.

in the Router0-1 ospf database:

    could you please include config for routers? especially router 0-3 – Datagram.Network Nov 23 '18 at 9:24

I tried your post experiment, when I in one area to assign R3's interface to Area1, the R2 will get this Error Receive logs.

But if you in R3 no router ospf 1, then launch a new OSPF process, and add the interface to Area 1 there will not get this fault.

and then show the Router2's OSPF database, there shows flawlessly.
