Chapter 25 Configuring MLPPP
Configuring MLPPP Backhaul
DETAILED STEPS
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
Command Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
Router(config-if)# interface serial
slot/port:channel-group-number
Example:
Router(config-if)# interface serial
0/5:5
Identifies and accesses the serial interface on the specified slot and port.
• channel-group-number—ID number to identify the channel group.
The valid range is from 0–30 for E1 controllers and 0–23 for T1
controllers.
Step 4
Router(config-if)# encapsulation
ppp
Example:
Router(config-if)# encapsulation
ppp
Enables PPP encapsulation on the serial interface.
Step 5
Router(config-if)# ppp multilink
Example:
Router(config-if)# ppp multilink
Enables multilink PPP on the serial interface.
Step 6
Router(config-if)# ppp multilink
group
group-n
umber
Example:
Router(config-if)# ppp multilink
group 5
Configures the serial interface as a member link to the multilink interface
identified by the group-number.
• group-number—Multilink group number.
The example identifies the multilink interface to which the serial interface
should be bound to as a member-link.
Step 7
Router(config-if)# exit
Example:
Router(config)# exit
Exits configuration mode.
