NOTE: Only MLPPP is supported on ACX Series routers. MLFR is not supported
on ACX Series routers.
Multilink and link services interfaces support the following logical interface encapsulation
types:
MLPPP
MLFR end-to-end
By default, the logical interface encapsulation type on multilink interfaces is MLPPP. The
default logical interface encapsulation type on link services interfaces is MLFR end-to-end.
For general information on encapsulation, see the Junos OS Network Interfaces Library
for Routing Devices.
You can also configure physical interface encapsulation on link services interfaces. For
more information, see Configuring Encapsulation for Link Services Physical Interfaces.
To configure multilink or link services encapsulation, include the
encapsulation type;
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]
You must also configure the T1, E1, or DS0 physical interface with the same encapsulation
type.
NOTE: ACX Series routers do not support DS0 physical interface as member
links.
CAUTION: When you configure the first MLFR encapsulated unit or delete
the last MLFR encapsulated unit on a port, it triggers an interface
encapsulation change on the port, which causes an interface flap on the other
units within the port that are configured with generic Frame Relay.
