Refer to the exhibit. R1 is able to ping the R3 fa0/1 interface. Why do the extended pings fail?
- A. The maximum packet size accepted by the command is 1476 bytes.
- B. R3 is missing a return route to 10.99.69.0/30
- C. R2 and R3 do not have an OSPF adjacency
- D. The DF bit has been set
Explanation: If the DF bit is set, routers cannot fragment packets. From the output below, we learn that the maximum MTU of R2 is 1492 bytes while we sent ping with 1500 bytes. Therefore these ICMP packets were dropped.
Note: Record option displays the address(es) of the hops (up to nine) the packet goes through.
