Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI

Configuration Sequence

Complete the following tasks to configure a multilink backhaul interface:

• Creating a Multilink Bundle, page 4-55

• Configuring PFC and ACFC, page 4-55

• Enabling Multilink and Identifying the Multilink Interface, page 4-57

• For more information about configuring MLPPP, see the Cisco IOS Dial Technologies

Configuration Guide, Release 12.2SR., page 4-58

Creating a Multilink Bundle

To create a multilink bundle, follow these steps while in the global configuration mode:

Step 1 Create a multilink bundle and enter the interface configuration mode:

Router(config)# interface multilink group-number

• group-number—Number of the multilink bundle.

For example, the following command creates a multilink bundle 5:

Router(config)# interface multilink5

Router(config-if)#

To remove a multilink bundle, use the no form of this command.

Note To see a list of the configuration commands available to you, enter ? at the prompt or press the

Help key while in the configuration mode.

Step 2 Assign an IP address to the multilink interface.

Router(config-if)# ip address address [subnet mask]

• address—The IP address.

• subnet mask—Network mask of IP address.

For example, the following command creates an IP address and subnet mask:

Router(config-if)# ip address 10.10.10.2 255.255.255.0

Configuring PFC and ACFC

Protocol-Field-Compression (PFC) and Address-and-Control-Field-Compression (AFC) are PPP

compression methods defined in RFCs 1661 and 1662. PFC allows for compression of the PPP Protocol

field; ACFC allows for compression of the PPP Data Link Layer Address and Control fields.

Use the following instructions to perform PFC and ACFC handling during PPP negotiation to be

configured. By default, PFC/ACFC handling is not enabled.

Note The recommended PFC and ACFC handling in the Cisco MWR 2941 router is: acfc local request, acfc

remote apply, pfc local request, and pfc remote apply.
