Re: forward protocol + dhcp helper address

Hi Imran,

As usual with the CCIE, the documentation is important but then validation
on your own kit to ensure that it's in alignment with reality.

"ip forward-protocol udp" appears to be less important these days and may
be a carry over from config examples based on older IOS versions

Looking in the 12.4T config guide for DHCP Relay Agent at
www.cisco.com/en/US/docs/ios-xml/ios/ipaddr_dhcp/configuration/12-4t/config-dhcp-relay-agent.htm

The thing about ip forward-protocol udp is you can send broadcasts for
other protocols over a routed network as well which may or may not be
useful and you may wish to "no ip forward-protocol udp xxx" for default
services you don't want sent beyond the LAN segment (though within the
scope of the R&S exam this may be overkill)

Cheers,
Adam
