Configuring
Configuring Bridging
| Command | Purpose |
Step 7 |
|
|
Assigns the Ethernet0 interface to a bridge group. | ||
|
| The bridge group must be an integer from 1 to 63. |
Step 8 |
|
|
Disables spanning tree on the Ethernet interface. | ||
|
| |
Step 9 |
|
|
Exits interface configuration mode for the Ethernet0 | ||
| uBR924(config)# interface | interface and enters interface configuration mode for |
|
| the cable access router interface. |
Step 10 |
|
|
Disables the IP address of the coaxial cable interface, | ||
|
| if one has been set. The Cisco uBR7200 series cable |
|
| router assigns an IP address to the cable access router |
|
| each time it connects to the network. |
Step 11 |
|
|
Disables | ||
|
| on the cable interface. |
Step 12 |
|
|
Disables keepalives on the cable interface. | ||
Step 13 |
|
|
Enables | ||
Step 14 |
|
|
Assigns the cable access router interface to a bridge | ||
|
| group. The bridge group must be an integer from 1 to |
|
| 63. (The default is 59.) |
Step 15 |
|
|
Disables spanning tree on the cable interface. | ||
|
| |
Step 16 |
|
|
Exits interface configuration mode. | ||
| uBR924(config)# ip classless | (Optional) At times, the Cisco uBR900 series might |
|
| |
|
| receive packets destined for a subnet of a network that |
|
| has no network default route. This global |
|
| configuration mode command allows the Cisco IOS |
|
| software to forward such packets to the best network |
|
| route possible. |
Step 17 |
|
|
uBR924(config)# line console 0 | Enters line configuration mode to configure the | |
|
| console port. |
Step 18 |
|
|
Identifies the last line in a contiguous group of virtual | ||
|
| terminals you want to configure. |
Step 19 |
|
|
Returns to privileged EXEC mode. | ||
| uBR924# copy | Saves the configuration to NVRAM so that it will not |
| configuration... | be lost in the event of a reset, power cycle, or power |
|
| |
|
| outage. |
|
|
|
When the cable interface comes up, the IP address and downstream channel are configured automatically.
Note To configure multiple PCs, repeat Steps 4 through 7 above for each additional PC. You can connect a maximum of three PCs to the Cisco uBR900 series cable access router in a bridging application.
