Explanation:
A DHCP relay agent is any host that forwards DHCP packets between clients and servers.
Relay agents receive DHCP messages and then generate a new DHCP message to send
out on another interface. The agents forward requests and replies between clients and
servers when they are not on the same physical subnet.
The Cisco IOS DHCP relay agent is enabled on an interface only when the ip helper-address
is configured.
If multiple helper-addresses are configured, it tries to get response from first, if no response
got from the first helper address then sends the request to second one.

  2. Brian says:

    Looking around Cisco Learning network, everyone appears to agree they are sent at the same time in a pseudo broadcast, despite the answer in the explanation. It is not normal for a router to hold onto any packet generated by another source in case no answer is received.

    The client will generally use the first offer it is sent.
