You have two routers in your OSPF area 0. Router 1 is connected to Router 2 via its Serial 1 interface, and to
your ISP via the Serial 0 interface. Router 1 is an ASBR.
After your assistant configures a default route on Router 1, you discover that whenever either router receives
packets destined for networks that are not in the routing tables, it causes traffic loops between the two routers.
To troubleshoot, you execute the show run command on Router 1. Part of the output is shown below:
<output omitted>
IP route 0.0.0.0 0.0.0.0 serial 1
Router ospf 1
Network 192.168.5.0 0.0.0.255 area 0
Default-information originate
Which command or set of commands should you execute on Router 1 to stop the looping traffic while
maintaining Router 2’s ability to send traffic to the Internet?
