R1 config:
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 default-information originate
Assume that OSPF has been correctly configured on router R2 and assume that all router interfaces are operational and correctly configured on all routers.

How will the default route configured on R1 affect the operation of R2?

A.	Any packet destined for a network that is not directly connected to router R1 will be dropped.
B.	Any packet destined for a network that is not directly connected to router R2 will be dropped immediately.
C.	Any packet destined for a network that is not directly connected to router R2 will be dropped immediately because of the lack of a gateway on R1.
D.	The networks directly connected to router R2 will not be able to communicate with the 172.16.10.0, 172.16.10.64, and 172.16.10.128 subnetworks.
E.	Any packet destined for a network that is not referenced in the routing table of router R2 will be directed to R1. R1 will then send that packet back to R2 and a routing loop will occur.
