Routing Mode Procedures
The Cisco 67x CPEs support two types of routing: PPP routing and RFC 1483
routing.
PPP Routing
Three Cisco 67x applications compose the PPP routing feature: DHCP server, and
Network Address Translation (NAT). With these applications enabled, you can
use the Cisco 67x without following the procedures described in this chapter such
as the “Bridging Mode Procedures” section on page 5-5 or the “Configure the
WAN Ports and ATM Virtual Connections” section on page 5-11. See the
following section to enable PPP routing.
Enabling PPP Routing
For each of the applications, the show application command reports if the feature
is enabled. Complete the following steps to enable the PPP routing feature for the
Cisco 67x. You must be in the enable mode to do this procedure.
Step 1 Enable the DHCP server:
set dhcp server enabled
