Explanation

A Type 1 LSA (Router LSA) is generated by every OSPF router and describes the router's directly connected links and their states within a single area. The output showing 'Router' in the LS Type field, along with the originating router's own Router ID as both the Link State ID and Advertising Router, is the hallmark of a Type 1 LSA. Type 2 is a Network LSA (generated by the DR), Type 3 is a Summary LSA (generated by an ABR), and Type 4 is an ASBR Summary LSA.
