On an OSPF network, all OSPF routers generate Router LSAs. If the E bit in a Router LSA is set to 1, the router that generates this LSA is a/an ______.
Router LSAs (Type 1 LSAs) are generated by every OSPF router to describe its directly connected links and their states.
The E (External) bit in the Options field of a Type 1 LSA indicates whether the router is acting as an Autonomous System Boundary Router (ASBR).
If E = 1, it means that the router is an ASBR, which means it is redistributing external routes (e.g., BGP, static routes) into OSPF.
IR (Internal Router), ABR (Area Border Router), and DR (Designated Router) do not set the E-bit in their Router LSA unless they are also ASBRs.
