Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line
Configuration Sequence
Step 2 Assign an IP address to the multilink interface.
Router(config-if)# ip address
address [subnet mask]
Where:
• 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
Handling PFC and ACFC
Use the following instructions to perform Protocol Field Compression (PFC) and Address and Control
Field Compression (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 3825 route r is: acfc local request, acfc remote
apply, pfc local request, and pfc remote apply.

Configuring PFC

To configure PFC handling during PPP negotiation, follow these steps, while in the interface
configuration mode:
Step 1 To configure how the router handles PFC in its outbound configuration requests, enter the following
command:
Router(config-if)# ppp pfc local {request | forbid}
Where:
• request—The PFC option is included in outbound configuration requests.
• forbid—The PFC option is not sent in outbound configurati on requests, and requests from a remote
peer to add the PFC option are not accepted.
For example, the following command creates how the router handles PFC:
Router(config-if)# ppp pfc local request
Step 2 To configure how the router handles the PFC option in configuration requests received from a remote
peer, enter the following command:
Router(config-if)# ppp pfc remote {apply | reject | ignore}
