Configuring Multilink Point-to-Point Protocol (Hardware-Based on the QFP)
Multilink Point-to-Point Protocol (MLPPP) allows you to combine interfaces which correspond to an entire
T1 or E1 multilink bundle. You can choose the number of bundles and the number of T1 or E1 lines in each
bundle in any combination of E1, T1, and NxDS0 member links interfaces.
On the Cisco ASR 1000 Series Router, MLPPP functionality is implemented on the Quantum Flow Processor
(QFP)—not the SPA. On other platforms that implement SPA-based MLPPP, the MLPPP member links must
reside on the same SPA—this is not a restriction on the Cisco ASR 1000 Series Aggregation Services Routers.
QFP-based MLPPP supports member links in the MLPPP bundle across different SPAs and SIPs on the Cisco
ASR 1000 Series Aggregation Services Routers.
For more information about configuring MLPPP in Cisco IOS XE software, see the
Media-Independent PPP and Multilink PPP"
Guide, Release 2
This section includes the following topics:
MLPPP Configuration Guidelines
When configuring MLPPP, consider the following guidelines:
• Only T1, E1, or NxDS0 links are supported in a bundle. The configuration will not prohibit higher
• Links of differing bandwidths are supported in the same bundle.
• PPP encapsulation must be enabled before configuring multilink-related commands.
Creating a Multilink Bundle
To create a multilink bundle, use the following commands:
SUMMARY STEPS
1. Router# configure terminal
2. Router(config)# interface multilink group-number
3. Router(config-if)# ip address address mask
