Section 4.2.4 says:
[...] If they are in different domains, and if routes from one are distributed into the other, the routes will appear as intra-network routes, which may not be what is intended.)
It should say:
[...] If they are in different domains, and if routes from one are distributed into the other, the routes will appear as inter-network routes, which may not be what is intended.)
Notes:
Inter-intra typo. Inter-network routes are used between the OSPF instances with the same Domain ID. With different Domain IDs, external-AS routes are applicable.
--VERIFIER NOTES--
The issue is that they will appear as intra-network routes while they are not.
