Introduction
Multilink PPP (MP) allows devices to send data over multiple point-to-point data links to the same destination by implementing a virtual link. The MP connection has a maximum bandwidth equal to the sum of the bandwidths of the component links. MP can be configured for either multiplexed links, such as ISDN and Frame Relay, or for multiple async lines. Refer to RFC 1990 
for more information on MP.
Note: RFC 1990 refers to Multilink PPP as MP. Other names by which MP is known include MPPP, MLP, and Multilink.
This setup explains setting up bandwidth aggregation using the NM-xAM cards routers connected through a plain old telephone service (POTS) line. Because multiple phone lines are often cheaper than ISDN Basic Rate Interface (BRI) service, async MP provides an effective way to increase connection speeds between remote sites while controlling costs. Async MP is also an effective way to obtain higher access speeds for remote areas that cannot be serviced by ISDN.
Async MP bundles together separate modem connections between end routers. PPP software on each peer fragments the packets and then transmits the pieces to the other side through the multiple analog connections. The receiving end gathers these pieces from the separate connections and, based on MP information embedded in them, reassembles the pieces into valid data packets, thus providing an end-to-end virtual link with higher bandwidth.

Components Used
The information in this document is based on the software and hardware versions below.
-
Cisco 2650 running Cisco IOS® Software Release 12.2(8)T5
-
Cisco 3640 running Cisco IOS Software Release 12.2(8)T
Note: MP was first introduced in Cisco IOS Software Release 11.0(3).
The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.
Configure
This configuration describes a remote Cisco 2650XM with an internal 8 port analog modem card (NM-8AM) dialing into a Cisco 3640 with NM-8AM. The configuration describes a multilink connection composed of three analog phone lines at either site. More phone lines can be configured for MP if they are available.
In this section, you are presented with the information to configure the features described in this document.
Note: To find additional information on the commands used in this document, use the Command Lookup Tool (registered customers only) .
Network Diagram
This document uses the network setup shown in the diagram below.
The Cisco 3600 and 2600 are a modular chassis. The line numbers for the NM-8AM card will depend on which slot its inserted in. Refer to How Async Lines are Numbered in Cisco 3600 Series Routers for more information.

Note: There is a dialer string for every peer phone number. The router will try each in sequence until one is successful. Hence, if all eight lines must be used in a multilink connection, then you need eight dialer strings. For the last connection the router will make seven unsuccessful calls before a successful eighth call.
In this configuration, only two lines are used for simplicity.

Tuning and Optional Commands
The following commands can be used to adjust the behavior of the MP connection. Careful adjustment of such parameters can help control costs by avoiding wasteful and unnecessary use of data links.
dialer load-threshold load [outbound | inbound | either]
MP can be configured so that additional channels come up immediately after the primary channel is established. To setup this scenario, set the load threshold value in the dialer load-thershold load command very low (ideal is around 3). In this case, the additional channels are brought up and continue to stay up (that is, they do not flap). If the load-threshold is set to any other value, the multiple channels may flap depending on the load across the link. If you want to have additional channels added as necessary, depending on the traffic, set the load-threshold to the appropriate value between 1 and 255. For example, for additional channels to come up at 50 percent, the threshold should be set to 128 (0.50*255). When determining the threshold, consideration must be given to the setup time for async calls because longer setup times may necessitate lower thresholds.
The load can be calculated based on outbound, inbound, or either the higher of the inbound or outbound traffic on the interface. If you base the load on inbound or either, ensure that the central site has passive-interface group-async1 configured so routing updates from the core are not sent via the async line. Preventing routing traffic from passing on the link provides more bandwidth for other data on the line.
ppp timeout multilink link remove seconds
This command may be used to prevent the multilink connections from flapping when the load varies. For example, when the load threshold is set to 15 (that is, 15/255=6%) and the traffic exceeds the threshold, additional lines are brought up. When the traffic falls below the threshold, the additional lines are dropped. In situations where data rates are highly variable, it is advantageous for the multiple channels to stay up for a specified period of time even if the load-threshold falls below the specified value. Assign this multilink timeout to be less than that specified for dialer idle-timeout which controls the timeout for all links.
ppp timeout multilink link add seconds
This command can be used to prevent multiple links from being added to the MP bundle until high traffic is received for a specified interval. This can prevent bursts of traffic from unnecessarily bringing up additional lines.
Verify and Troubleshoot
This section provides information you can use to confirm your configuration is working properly and troubleshoot any problems.
Certain show commands are supported by the Output Interpreter Tool (registered customers only) , which allows you to view an analysis of show command output.
Note: Before issuing debug commands, please see Important Information on Debug Commands.
-
show ppp multilink - Displays information on multilink bundles that are active. This command should be used to verify the multilink connection.
-
debug ppp multilink events - Displays information about events affecting multilink bundles.
-
debug ppp negotiation - Displays information on the PPP traffic and exchanges while negotiating Link Control Protocol (LCP), Authentication, and Network Control Protocol (NCP). A successful PPP negotiation will first open the LCP state, then authenticate, and finally negotiate NCP. Multilink parameters such as Maximum Receive Reconstructed Unit (MRRU) are established during LCP negotiation.
-
debug modem - Displays modem line activity on an access server.
-
debug dialer - Verifies that the the dialer is dialing correctly.
-
debug chat - Verifies that the the dialer is dialing correctly.
Verify that PPP negotiation and authentication is successful. Pay attention to the LCP negotiation where MP parameters line MRRU and the Endpoint Discriminator (EndpointDisc) are negotiated. Verify that the link is virtualized correctly. A Virtual Access interface will be created by the Cisco IOS Software to represent the MP bundle. Verify that Internet Protocol Control Protocol (IPCP) negotiation was successful. Note whether correct IP addresses were assigned and whether the proper routes were installed.
When testing your MP configuration, ensure that you are generating enough traffic across the link to trigger the load threshold. You can adjust the load-threshold value during your test as necessary.

The show ppp multilink command can be used to verify if a multilink bundle has been created for the connection. Even if only one connection is active, a multilink connection is created with the assumption that more connections will be established.
