The Type 2 LSA represents a multi-access network segment (such as Ethernet) that utilises a DR/BDR.
The DR always advertises the Type 2 LSA, which identifies all routers attached to the multi-access network segment.
If a DR is not yet elected in the segment, there are no Type 2 LSAs in the LSDB. If a new DR is elected or changed, a new Type 2 LSA is created.
Type 2 LSAs are not flooded outside of an area.
