Subject: DHCP relay - RFC 2131 clarification

I have a question concerning the DHCP relay agent.

According to RFC 2131 DHCP relay works on the following way:
If 'giaddr' in the discover message is non-zero the DHCP
server sends the offer to the server port (port 67) on the
host whose address appears in 'giaddr'.

Questions:
Is it mandatory for a DHCP server which is compliant to RFC
2131 to support DHCP relay?
Is DHCP relay a feature that MUST be implemented or a feature
that SHOULD be implemented in the DHCP server?

Kind regards,
