R1 configuration:
ip route 0.0.0.0 0.0.0.0 serial0/0
router ospf 1
network 172.16.10.0 0.0.0.3 area 0
network 172.16.10.64 0.0.0.63 area 0
network 172.16.10.128 0.0.0.31 area 0

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?
| A. |
Router R2 will not form a neighbor relationship with R1. | |
| B. |
Router R2 will obtain a full routing table, including a default route, from R1. | |
| C. |
R2 will obtain OSPF updates from R1, but will not obtain a default route from R1. | |
| D. |
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.
