Michael,
Some of the links below might be of help:
http://www.cisco.com/warp/public/707/21.html#directed-bcast
http://www.cisco.com/univercd/cc/td/doc/product/atm/c8540/12_0/13_19/cmd_ref
/i.htm#xtocid12
Basically ip directed-broadcast is used forward broadcast as unicast to its
destionation in case that ip helper-address is employed to forward
broadcast, ip forward protocol is to define what kind of protocol will be
forwarded instead of the default protocols:
Trivial File Transfer Protocol (TFTP) (port 69)
Domain Naming System (port 53)
Time service (port 37)
NetBIOS Name Server (port 137)
NetBIOS Datagram Server (port 138)
Boot Protocol (BOOTP) client and server datagrams (ports 67 and 68)
TACACS service (port 49)
IEN-116 Name Service (port 42)
You may also want to use no ip forward-protocol to modify default protocols.
Hope it helps,
Tony

Hi, group
Could someone please explain what is these commands doing?
I have a hard time understand the Cisco Doc.
An example would be great, too.
Thanks
