Hi,
You are right. There is a mistake of this example in DocCD. I have done a
lab in DoiT workbook from netmasterclass (www.netmasterclass.com), which
gives a very good pratice of this feature.
Moreover, in order to generate UDP packets for testing without any
traffic generator, you can use extended traceroute.
Best Regards,
William Chen

Subject: ip multicast helper-map - ip directed broadcast

stream at the incoming interface of the last hop router, is sent out on the
outgoing interface as physical broadcast using default interface
configuration.

> Because this interface will just drop the directed broadcast arriving at
the interface. In order to prevent this from happening the command "ip
directed broadcast should" be configured on the outgoing interface of the
last hop router.

> Since this example doesn't say anything about that, I'm still wondering if
this is correct, could somebody confirm this?
