Chapter 25 Configuring MLPPP

Configuring MLPPP Backhaul

DETAILED STEPS

	Command	Purpose
Step 1
	enable	Enables privileged EXEC mode.
		• Enter your password if prompted.
	Example:
	Router> enable
Step 2
	configure terminal	Enters global configuration mode.
	Example:
	Router# configure terminal
Step 3
	Router(config-if)# interface serial	Identifies and accesses the serial interface on the specified slot and port.
	slot/port:channel-group-number	• channel-group-number—ID number to identify the channel group.
	Example:	The valid range is from 0–30 for E1 controllers and 0–23 for T1
		controllers.
	Router(config-if)# interface serial
	0/5:5
Step 4
	Router(config-if)# encapsulation	Enables PPP encapsulation on the serial interface.
	ppp
	Example:
	Router(config-if)# encapsulation
	ppp
Step 5
	Router(config-if)# ppp multilink	Enables multilink PPP on the serial interface.
	Example:
	Router(config-if)# ppp multilink
Step 6
	Router(config-if)# ppp multilink	Configures the serial interface as a member link to the multilink interface
	group group-number	identified by the group-number.
	Example:	• group-number—Multilink group number.
		The example identifies the multilink interface to which the serial interface
	Router(config-if)# ppp multilink
		should be bound to as a member-link.
	group 5
Step 7
	Router(config-if)# exit	Exits configuration mode.
	Example:
	Router(config)# exit

MLPPP Offload

By default, the Cisco ASR 901 router offloads processing for distributed MLPPP (dMLPPP) to the network processor for improved performance. However, the Cisco ASR 901 does not support some dMLPPP settings on offloaded bundles. The Cisco ASR 901 does not support the following options on offloaded dMLPPP bundles:

•ppp multilink idle-link

•ppp multilink queue depth
