a switch or router, and to compare the link state databases of two devices. AS_OPAQUE LSA
Checksum
The number of LSAs originated by the switch.
In any OSPF area, a router (or in this situation, a switch) originates several LSAs. Each
router originates a router-LSA. If the router is also the designated router for any of the
area’s networks, it originates network LSAs for those networks.
New LSAs Originated
The number of received LSAs for new instantiations. This number does not include
new instantiations of self-originated LSAs. LSAs Received
