Configuring Bridging

The Cisco uBR900 series cable access router is configured for DOCSIS-compliant transparent bridging by default. If it becomes necessary to reconfigure the unit for bridging after it has been configured for routing, you can erase the routing configuration and return the unit to factory default configuration settings, or you can reconfigure the unit manually using the CLI. To return the cable access router to factory default settings, see the “Reestablishing DOCSIS-Compliant Bridging” section later in this chapter for details. To reconfigure the cable access router manually, use the following commands, beginning in global configuration mode:

	Command	Purpose
Step 1
Step 1	uBR924(config)# no service pad	Disables packet assembler/disassembler (PAD)
		commands; prevents the Cisco uBR900 series from
		accepting incoming or outgoing PAD connections.
Step 2
Step 2	uBR924(config)# no service password-encryption	Disables password encryption.
Step 3
Step 3	uBR924(config)# no ip routing	Disables IP routing on the Cisco uBR900 series.
Step 4
Step 4	uBR924(config)# interface Ethernet0	Enters interface configuration mode for the Ethernet0
		interface.
Step 5
Step 5	uBR924(config-if)# no ip address	Disables the IP address on the Ethernet0 interface.
Step 6
Step 6	uBR924(config-if)# no ip route-cache	Disables high-speed switching caches for IP routing.
