Refer to the exhibit. The default route is not advertised to the neighboring router. Which action resolves the issue?

  • A Configure the default-information originate command under OSPF
  • B Configure OSPF on the Dialer0 interface.
  • C Configure the redistribute static metric 200 subnets command under OSPF.
  • D Configure the network 0.0.0.0 255.255.255.255 area 0 command under OSPF
Explanation

OSPF does not automatically advertise default routes; the 'default-information originate' command must be configured on the router originating the default route. This command tells OSPF to inject a 0.0.0.0/0 route into the routing domain. Configuring OSPF on additional interfaces, static redistribution, or the network command do not accomplish default-route advertisement.
