Which of the following devices can originate an opaque LSA?
An opaque LSA (Link-State Advertisement) is a type of LSA used in OSPF (Open Shortest Path First) networks to support various extensions, such as Traffic Engineering (TE). These types of LSAs can be originated by any OSPF router that is TE-enabled, including backbone routers, ABRs (Area Border Routers), and ASBRs (Autonomous System Boundary Routers). Therefore, TE-enabled OSPF routers specifically have the capability to originate opaque LSAs.
In addition to the LSA types described above, there is another class of LSAs, known as Opaque LSAs. These LSAs were defined in RFC 2370 to support extensions to the OSPF protocol.
