Subscriber-End Broadband Access Router Configuration Options

The Cisco uBR900 series cable access router typically ships from the factory ready to work in the Base IP Bridging Feature Set (DOCSIS-compliant bridging) data-only mode. The cable access router is configured automatically at startup by one or more configuration file generated by the cable service provider and downloaded to the router; no configuration or setup is required other than to connect the router to the cable system. The CMTS provides a path from the cable access router to the DHCP server for PC address assignment.

The PCs connected to the Cisco uBR900 series must be configured for IP. Using DHCP, the CMTS assigns an IP subnet address to the cable access router each time it connects to the network. The IP addresses of the cable access router and the individual PCs attached to it enable the CMTS to route data to and from the PCs.

Note When the Cisco uBR900 series cable access router is shipped from the factory, it is configured by default for DOCSIS-compliant bridging.

The configuration file or files downloaded to the Cisco uBR900 series by the CMTS at the headend are dependent on the services purchased by the individual cable service subscriber. The cable access router is provisioned in the following manner:

•When the cable access router is first brought online, the CMTS downloads a binary file to the router that is in DOCSIS-specified format. This file configures the router for the desired level of service and sets other parameters as needed.

•If additional features are required beyond basic DOCSIS-compliant bridging, the DOCSIS configuration file can specify a Cisco IOS image that the CMTS should also download to the router. (To speed up the time required to bring the router online, the cable service provider can preload the Cisco uBR900 series with the appropriate image at the warehouse.)

•To customize the cable access router configuration further, the DOCSIS configuration file can also specify a Cisco IOS configuration file that the CMTS should download to the router. This second configuration file is an ASCII text file that contains the Cisco IOS commands needed to further configure the router as desired.

Note The CMTS typically downloads the DOCSIS configuration file, Cisco IOS image (if needed), and the Cisco IOS configuration file (if needed) only once when the router is initially brought online. However, a new configuration file or image can be downloaded whenever necessary, such as when the cable service provider offers new services or subscribers upgrade their services.

To ensure that you obtain the exact services that you have ordered, the Cisco uBR900 series arrives from the factory with a unique identifier (UID) that consists of a serial number and MAC address. These factory-assigned values are on a label at the bottom of the cable access router; for convenience, these values are also in a barcode label that can be easily scanned for entry into the service provider provisioning and billing system.
