UDP broadcast flooding - DOIT Lab8.16

Hi Group!

There is only one small question:

Cisco doc says: "Regardless of whether you implement IP helper
addressing or UDP flooding, you must use the ip forward-protocol udp
global configuration command to enable the UDP forwarding. By default,
the command enables forwarding the protocols: TFTP, DNS, NTP, NetBIOS
Name Server, NetBIOS Datagram Server, BOOTP and TACACS. To enable
forwarding for other ports, you must specify them as arguments to the
ip forward-protocol udp command."

...and then: "The key commands for enabling UDP flooding are as follows:

bridge group protocol protocol
ip forward-protocol spanning tree
bridge-group group input-type-list access-list-number"

DOIT Lab 8.16 AK configs include only "ip forward-prot spann" command.
There is no "ip forward-protocol udp" command on any router/switch
config participating in the broadcast flooding domain.

So do I have to configure the ip forward-protocol udp command, if
there is a need to run UDP broadcast propagation using UDP Flooding
feature and/or IP Helper Addressing?

Best Regards
