Example: Configuring an MLPPP Bundle
This example shows how to configure an MLPPP bundle to increase traffic bandwidth.
Requirements
Before you begin, you should have two MX Series routers (MX240, MX480, or MX960 routers) configured with at least two serial interfaces that communicate over serial links.
Overview
In this example, you create the MLPPP bundle lsq-0/0/0.0 at the logical unit level of the link services interface lsq-0/0/0 on the MX Series routers R0 and R1. You then add the two serial interfaces se-1/0/0 and se-1/0/1 as constituent links to the multilink bundle. In Figure 1, your company's branch office is connected to its main branch using routers R0 and R1. You transmit data and voice traffic on two low-speed 1-Mbps serial links. To increase bandwidth, you configure MLPPP and join the two serial links se-1/0/0 and se-1/0/1 into the multilink bundle lsq-0/0/0.0. Then you configure LFI and CoS on R0 and R1 to enable them to transmit voice packets ahead of data packets.

To quickly configure this example, copy the
following commands, paste them into a text file, remove any line breaks,
change any details necessary to match your network configuration,
and then copy and paste the commands into the CLI at the [edit] hierarchy level.
For device R0 set interfaces lsq-0/0/0 unit 0 family inet address 10.0.0.10/24 set interfaces se-1/0/0 unit 0 family mlppp bundle lsq-0/0/0.0 set interfaces se-1/0/1 unit 0 family mlppp bundle lsq-0/0/0.0 set interfaces se-1/0/0 serial-options clocking-mode dce clock-rate 2.0mhz set interfaces se-1/0/1 serial-options clocking-mode dce clock-rate 2.0mhz
For device R1 set interfaces lsq-0/0/0 unit 0 family inet address 10.0.0.9/24 set interfaces se-1/0/0 unit 0 family mlppp bundle lsq-0/0/0.0 set interfaces se-1/0/1 unit 0 family mlppp bundle lsq-0/0/0.0
Step-by-Step Procedure
The following example requires you to navigate various levels in the configuration hierarchy. For instructions on how to do that, see Using the CLI Editor in Configuration Mode in the Junos OS CLI User Guide.
To configure MLPPP bundle:
Create an interface on both the routers.
[edit] user@host# edit interfaces lsq-0/0/0 unit 0
Configure a family inet and define the IP address on device R0.
[edit interfaces lsq-0/0/0 unit 0] user@host# set family inet address 10.0.0.10/24
Configure a family inet and define the IP address on device R1.
[edit interfaces lsq-0/0/0 unit 0] user@host# set family inet address 10.0.0.9/24
Specify the names of the constituent links to be added to the multilink bundle on both the routers.
[edit interfaces] user@host# edit se-1/0/0 unit 0 user@host# set family mlppp bundle lsq-0/0/0.0 [edit interfaces] user@host# edit se-1/0/1 unit 0 user@host# set family mlppp bundle lsq-0/0/0.0
Set the serial options to the same values for both interfaces on R0.
Note:R0 is set as a DCE device. The serial options are not set for interfaces on R1. You can set the serial options according to your network setup.
[edit interfaces] user@host# set se-1/0/0 serial-options clocking-mode dce clock-rate 2.0mhz user@host# set se-1/0/1 serial-options clocking-mode dce clock-rate 2.0mhz
Results
From configuration mode, confirm your configuration
by entering the show interfaces lsq-0/0/0, show interfaces
se-1/0/0, and show interfaces se-1/0/1 commands for
R0 and R1. If the output does not display the intended configuration,
repeat the configuration instructions in this example to correct it.
For device R0
[edit]
user@host# show interfaces lsq-0/0/0

}
}

Example: Configuring Inline MLPPP and Multilink Frame Relay End-to-End (FRF.15) for WAN Interfaces
Inline Multilink PPP (MLPPP), Multlink Frame Relay (FRF.16), and Multilink Frame Relay End-to-End (FRF.15) for time-division multiplexing (TDM) WAN interfaces provide bundling services through the Packet Forwarding Engine without requiring a PIC or Dense Port Concentrator (DPC).
This example shows how to configure a Multilink PPP (MLPPP) bundle and Multilink Frame Relay End-to-End (FRF.15) for additional bandwidth, load balancing, and redundancy by aggregating low-speed links such as T1 (WAN interfaces).
Requirements
This example uses the following hardware and software components:
Two MX Series Routers
Junos OS Release 14.1 or later release
Before you begin, configure two MX Series routers (the MX240, MX480, or MX960) with at least two WAN interfaces that communicate over T1 links.
Overview
Traditionally, bundling services are used to bundle multiple low-speed links to create a higher bandwidth pipe. This combined bandwidth is available to traffic from all links and supports link fragmentation and interleaving (LFI) on the bundle, reducing high-priority packet transmission delay.
This support includes multiple links on the same bundle as well as multiclass extension for MLPPP. Through this service you can enable bundling services without additional DPC slots to support Service DPC and free up the slots for other MICs.
Configuring inline MLPPP for WAN interfaces benefits the following services:
CE-PE link for Layer 3 VPN and DIA service with public switched telephone networks (PSTN)-based access networks
PE-P link when PSTN is used for MPLS networks
In this example, to increase bandwidth, you configure MLPPP
and join the T1 links into the multilink bundle. You aggregate T1
links to create the MLFR FRF.15 bundle on two MX Series routers, R0
and R1, and set the interface to lsq-. You configure logical
units on the lsq- interface and set the family type to inet and an IP address. Then you configure an IP address for
the multilink bundle on the unit level of the interface. You define
the multilink bundle as an MLFR FRF.15 bundle by specifying the MLFR
end-to-end encapsulation type. You specify the names of the constituent
links to be added to the multilink bundle and set the encapsulation
type to frame-relay. You then define Router R0 as a DCE
device and Router R1 as a DTE device. You set the DLCI value (range
is from 16 through 1022). Finally, you set the multilink bundle to lsq-.
