Basic Internet Access Routing Configuration Example
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.
