C ONFIGURING A DVANCED IP R OUTING
DHCP Relay Agent
Remote Bridge to IP Router (w/Relay Agent)
This configuration is useful when requests by a DHCP Client must be “bridged” to an IP Router
that is also a DHCP/BOOTP Relay Agent. Our equipment is shown in this example, but any remote
bridge device should work.
In this configuration, the DHCP Client is able to obtain its IP address from the DHCP Server (and
any other information that the server provides), using the Relay Agent contained in the DHCP-
enabled router “Alex.” “Ruby” is a remote bridge device which communicates with the IP router
using a RLAN interface. Sample configurations for the objects in the above network diagram are:
