Refer to the exhibit. In this network,R1 has been configured to advertise a summary route, 192.168.0.0/22,to R2. R2 has been configured to advertise a summary route,192.168.0.0/21, to R1. Both routers have been configured to remove the discard route (the route to null created when a summary route is configured) by setting the administrative distance of the discard route to 255. What will happen if R1 receives a packet destined to 192.168.3.1? ()
A.The packet will loop between R1 and R2
B.It is not possible to set the administrative distance on a summary to 255
C.The packet will be forwarded to R2,where it will be routed to null0
D.The packet will be dropped by R1,since there is no route to 192.168.3.1
