Well, no, I read the RFC the same way, so I wouldn't agree
with your relay vendor.
The RFC discusses only the client<->server model...not the
client<->relay<->server model (at least, not explicitly).
Because the minimum IP MTU is 576, I think a relay is justified
in not accepting larger packets...if their MTU is really 576.
I would say that a relay needs to support DHCP packets up to
their MTU size.
But I also would say it is terribly unfair of the Cisco device
to send a 604 byte packet when the trailing bytes are all zero.
