Module Requirements

For information about the modules that support MLFR interfaces on ERX14xx models,
ERX7xx models, and the ERX310 router:

Interface Specifiers

The interface specifier format that you use depends on the type of physical interface
on which you want to configure MLFR.
For more information about supported interface types and specifiers on E Series
routers, see Interface Types and Specifiers in JUNOSe Command Reference Guide.

Logical aggregation of up to eight T1 or E1 links in a bundle
Monotonically increasing sequence numbers for each circuit
All packets distributed across the member links have monotonically increasing
sequence numbers for each circuit. This feature enables the remote router on
the customer premises to perform resequencing (if it is configured to do so).
Static configuration of the links participating in a multilink bundle
Round-robin packet distribution
On CT3 line modules, packet distribution across the member links in a bundle
is handled only in a round-robin fashion. The round-robin approach is used
even when the member links have different line rates.
On cOCx/STMx and COCX-F3 line modules, the router keeps track of the
link with the least traffic. If this link cannot forward a packet, the router
