Assume that all of the router interfaces are operational and configured correctly.
How will router R2 be affected by the configuration of R1 that is shown in the exhibit?
Router R2 will not form a neighbor relationship with R1.
Router R2 will obtain a full routing table, including a default route, from R1.
R2 will obtain OSPF updates from R1, but will not obtain a default route from R1.
R2 will not have a route for the directly connected serial network, but all other directly connected networks will be present, as well as the two Ethernet networks connected to R1.
Default routes injected into a normal area can be originated by any OSPF router. The OSPF router does not, by default, generate a default route into the OSPF domain. In order for OSPF to generate a default route, you must use the default-information originate command.
Static default route is exist in R1. It's wrong, but it is exist. So router R1 originates a type 5 LSA with a link ID of 0.0.0.0.
