Integrated Routing and Bridging (IRB) —(Recommended) The IRB feature allows your Cisco DSL Router to bridge traffic in on its ATM interface (the ADSL interface) and then route that traffic out on its Ethernet interface. With IRB enabled, the Cisco DSL Router can perform value-added services such as Network Address Translation (NAT) overload, NAT Pool, Static NAT, and Dynamic Host Control Protocol (DHCP) Server.
Pure Bridging —In a Pure Bridging implementation, your Cisco DSL Router acts as a simple ADSL to Ethernet bridge, and is unable to provide value-added services.
