Configuring DHCP Option 82 for RBE
To configure DHCP Option 82 support for RBE connections, enter the following commands beginning
in global configuration mode:
Command
Step 1
Router(config)# ip dhcp relay information
option
Step 2
Router(config)# rbe nasip source_interface
Example 3-7
information option command. The rbe nasip command configures the router to forward the IP address
for Loopback0 to the DHCP server. The value (in hexadecimal) of the agent remote ID suboption is
010100000B0101814058320 and the value of each field is the following:

enables DHCP option 82 support on the DHCP relay agent by using the ip dhcp relay
Port Type: 0x01
Version: 0x01
Purpose
Redistributes routes from one routing domain into another
routing domain.
The protocol argument is the source protocol from which
routes are being redistributed. It can be one of the following
keywords: bgp, connected, egp, igrp, isis, ospf, static [ip],
or rip.
The connected keyword refers to routes that are established
automatically by virtue of having enabled IP on an interface.
Exits address family configuration mode.
Enters address family configuration mode for configuring
BGP routing sessions that use standard Virtual Private
Network (VPN) Version 4 address prefixes.
(Optional) The unicast keyword specifies VPN Version 4
unicast address prefixes.
Activates route exchanges with the global BGP neighbors.
Specifies that a community attribute should be sent to a BGP
neighbor.
The both keyword specifies that both community attributes
should be sent.
Exits address family configuration mode.
Exits router configuration mode.
Creates a point-to-point ATM subinterface. Enters
subinterface configuration mode.
Enables RBE on the subinterface.
Purpose
Enables the system to insert the DHCP relay agent
information option in VPN suboptions.
Specifies the IP address of an interface on the DHCP relay
agent. This is the interface address that is sent to the DHCP
server in the agent remote ID suboption.
