I think you can use *ip multipath round robin* command. Explanation below :
*Configuring Equal-Cost Multipath Load Sharing
*
Equal-cost multipath (ECMP) sets are formed when the system finds
routing table entries for the same destination with equal cost. You can
add routing table entries manually (as static routes), or they are
formed as routers discover their neighbors and exchange routing tables
(via OSPF, BGP, and other routing protocols). The system then balances
traffic across these sets of equal-cost paths using one of the following
ECMP modes:
* Hashed - uses hashing of source and destination addresses to
determine which of the available paths in the ECMP set to use
* Round-robin - distributes packets equally among the available
paths in the ECMP set
* ip multipath round-robin*
* Use to specify round-robin as the mode for ECMP load sharing on an
interface.
* ECMP uses the round-robin mode when you have configured all
interfaces in the set to round-robin. Otherwise, ECMP defaults to hashed
mode because round-robin mode could cause reordering of packets. You
must explicitly ensure that the possible reordering is acceptable on all
the member interfaces by setting them to round-robin mode.
* Use the no version to set the ECMP mode to the default, hashed.
Example :
host1(config)#virtual-router router_0
host1:router_0(config)#interface serial 4/0:1/22.22
host1:router_0(config-subif)#ip multipath round-robin
host1:router_0(config-subif)#exit

Hi All,
Does juniper ERX support per packet load balancing ?
Is there a way to force this behavior?
Thanks
