[cisco-nas] Did IOS change behaviour for Type-5 OSPF linksrecently?

[Andrey Kostin]

Hello Peter,
In Cisco IOS Software Release 12.1(3) and later, the Type-5 LSAs are no
longer created for connected networks included in the network statements
under router OSPF then redistribute connected is configured.
So, if you have network statement under ospf process "overlapping" with
redistribute connected network, you will lose Type-5 LSA in OSPF database in
favor of internal LSA.
