Bridge with DHCP relay
The EtherXtend enables bridges to be configured as DHCP relay agents. All
DCHP messages on the bridge will have Option 82 information inserted and
be passed up through an IP interface to a external DHCP server.
Figure 15 illustrates the traffic flow when the EtherXtend is configured with
bridges to support DHCP relay.
