in RFC 2328(for ospf) i see that Link-State-Id and Advertising-Router-Id are same for Router-LSAs(type1).
For router-LSAs, this field is identical to the Link State ID field. Network-LSAs are originated by the network's Designated Router. Summary-LSAs originated by area border routers. AS-external-LSAs are originated by AS boundary routers.
But in my understanding both fields will have same value even for Type-2(Network LSAs). is my understanding right?
