Example: Configuring Multilink Frame Relay FRF.16
This example shows how to configure MLFR FRF.16 for additional bandwidth, load balancing, and redundancy.
Requirements
Before you begin, you should have two MX Series 5G Universal Routing Platforms configured with at least two serial interfaces that communicate over serial links.
Overview
In this example, you aggregate two T1 interfaces to create an MLFR FRF.16 bundle on two MX Series, R0 and R1. You configure the chassis interface and specify the number of MLFR FRF.16 bundles to be created on the interface. You then specify the channel to be configured as a multilink bundle and create interface lsq-0/0/0:0. You set the multilink bundle as an MLFR FRF.16 bundle by specifying the MLFR UNI NNI encapsulation type.
Then you define R0 as a DCE device and R1 as a DTE device. You configure a logical unit on the multilink bundle lsq-0/0/0:0, and set the family type to inet. You then assign a DLCI of 400 and an IP address of 10.0.0.10/24 to the multilink bundle. You create the T1 interfaces, t1-2/0/0 and t1-2/0/1, that are to be added as constituent links to the multilink bundle and define the Frame Relay encapsulation type. Finally, you set the multilink bundle to lsq-0/0/0:0.

Example: Configuring Multilink Frame Relay FRF.15
This example shows how to configure MLFR FRF.15 for additional bandwidth, load balancing, and redundancy by aggregating low-speed links such as T1, E1, and serial links.
Requirements
Before you begin, you should have two MX Series 5G Universal Routing Platforms (MX240, MX480, or MX960 routers) configured with at least two serial interfaces that communicate over serial links.
Overview
In this example, you aggregate two T1 links to create the MLFR
FRF.15 bundle on two MX Series routers, R0 and R1, and set the interface
to lsq-0/0/0. You configure a logical unit on the lsq-0/0/0 interface
and set the family type to inet
with address 10.0.0.4/24.
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
as t1-2/0/0 and t1-2/0/1 and set the encapsulation type to frame-relay
. You then define R0 as a DCE device and R1 as a DTE device. You
set the DLCI value to 100 (range is from 16 through 1022). Finally,
you set the multilink bundle to lsq-0/0/0.0.

Configuring DLCIs on Link Services Logical Interfaces
For link services interfaces only, you can configure multiple DLCIs for MLFR FRF.16 or MLPPP bundles.
DLCIs are not supported on multilink interfaces.
- Configuring Point-to-Point DLCIs for MLFR FRF.16 and MLPPP Bundles
- Configuring Multicast-Capable DLCIs for MLFR FRF.16 Bundles
Configuring Point-to-Point DLCIs for MLFR FRF.16 and MLPPP Bundles
For link services interfaces only, you can configure multiple
point-to-point DLCIs for each MLFR FRF.16 or MLPPP bundle. A channelized
interface, such as ls-1/1/1:0
, denotes a single MLFR FRF.16
bundle. To configure a DLCI, include the dlci
statement:
dlci dlci-identifier;
You can include this statement at the following hierarchy levels:
[edit interfaces interface-name unit logical-unit-number]
[edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]
The DLCI identifier is a value from 16 through 1022. Numbers 1 through 15 are reserved for future use.
When you configure point-to-point connections, the maximum transmission unit (MTU) sizes on both sides of the connection must be the same.
Configuring Multicast-Capable DLCIs for MLFR FRF.16 Bundles
For link services interfaces only, you can configure multiple
multicast-capable DLCIs for each MLFR FRF.16 bundle. A channelized
interface, such as ls-1/1/1:0
, denotes a single MLFR FRF.16
bundle. By default, Frame Relay connections assume unicast traffic.
If your Frame Relay switch performs multicast replication, you can
configure the link services connection to support multicast traffic
by including the multicast-dlci
statement:
multicast-dlci dlci-identifier;
You can include this statement at the following hierarchy levels:
[edit interfaces interface-name unit logical-unit-number]
[edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]
The DLCI identifier is a value from 16 through 1022 that defines the Frame Relay DLCI over which the switch expects to receive multicast packets for replication.
You can configure multicast support only on point-to-multipoint link services connections. Multicast-capable DLCIs are not supported on multilink interfaces.
If keepalives are enabled, causing the interface to send Local Management Interface (LMI) messages during idle times, the number of possible DLCI configurations is limited by the MTU selected for the interface. For more information, see Configuring Keepalives on Link Services Physical Interfaces.

Example: Configuring Inline Multilink Frame Relay (FRF.16) for WAN Interfaces
Inline Multilink PPP (MLPPP), Multilink 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).
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.
This example shows how to configure Multilink Frame Relay (FRF.16) 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
In this example, you aggregate T1 interfaces to create an MFR
FRF.16 bundle on two MX Series routers, R0 and R1. You configure the
chassis interface and specify the number of MFR FRF.16 bundles to
be created on the interface. You then specify the channel to be configured
as a multilink bundle and create interface lsq-
. You set
the multilink bundle as an MFR FRF.16 bundle by specifying the multilink-frame-relay-uni-nni
encapsulation type. Then you
define Router R0 as a DCE device and Router R1 as a DTE device. You
configure a logical unit on the multilink bundle lsq-
,
and set the family type to inet
. You create the T1 interfaces,
that are to be added as constituent links to the multilink bundle
and define the Frame Relay encapsulation type. Finally, you set the
multilink bundle to lsq-
.
