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.

Current configuration:

!

version 12.1 service config no service pad

service timestamps debug uptime service timestamps log uptime no service password-encryption

!

hostname uBR904

!

clock timezone - 4 ip subnet-zero

!

voice-port 0

!

voice-port 1

!
