Basic Internet Access Routing Configuration

The Cisco uBR900 series cable access router can be configured to act as a router to preserve IP

address space and limit broadcasts that can impact the performance of the network. A sample

configuration file follows.

Note To configure the Cisco uBR900 series to act as a router, the no cable-modem compliant

bridge command must be used. In addition, the bridge group 59 command must be removed from

the Ethernet and cable-modem interfaces.
