DHCP Relay and ip forward-protocol command
With srg's questions on DHCP, I've revisited dhcp relay and ran through some tests using "ip forward-protocol" command. With GNS3 12.4 code, seeing that the command is neither sufficient nor necessay when using "ip helper-address" to forward DHCP packets to the server. Only command necessary is "sevice dhcp". Doesn't that contradict Usage Guidelines for ip helper-address? Is this a bug in the my code?
I turned on "debug ip udp" and didn't see any forwarding output. Then disabled "ip forward-protocol" but still, dhcp relay forwards the discoveries to server.
Guessing that the "ip forward-protocol udp bootps" is just that, to forward to a bootp server ?
Second note: Vice ip helper-address, why not use a relay pool, which appears to not forward tftp, dns and such? Again testing with GNS3
