White Paper Abstract:
This document describes the DHCP Option 82 Support for Routed Bridge Encapsulation features.
The DHCP relay agent information option (option 82) enables a Dynamic Host Configuration Protocol
(DHCP) relay agent to include information about itself when forwarding client-originated DHCP
packets to a DHCP server. The DHCP server can use this information to implement IP address or other
parameter-assignment policies.
The DHCP Option 82 Support for Routed Bridge Encapsulation feature provides support for the DHCP
relay agent information option when ATM routed bridge encapsulation (RBE) is used. Figure 1 shows a
typical network topology in which ATM RBE and DHCP are used. The aggregation router that is using
ATM RBE is also serving as the DHCP relay agent.
