Section 7: IOS and IP Features (14 Points)
Ensure that when pinging to destination 10.80.80.255 from R3 that R1, R6, R8, and Switch1 reply.
By default, the broadcast ping will be terminated by R1 but it will itself respond to the ping. By configuring R1 with the command ip directed-broadcast on Fast Ethernet0/0, R1 will then forward the ping to the whole destination subnet, which will result in R6, R8, and Switch1 also replying to the ping.
Example 2-72 shows verification of a broadcast ping to 10.80.80.255 initiated from R3 with replies received from R1, R6, R8, and Switch1.
If you have configured this correctly, you have scored 3 points.
