To complete the configuration you must apply the routing policy to routes exported from
the routing table to the forwarding table, by including the policy name in the list specified
by the statement:
export
export [ policy-names ];
You can include this statement at the following hierarchy levels:
[edit routing-options forwarding-table]
[edit logical-systems logical-system-name routing-options forwarding-table]
By default, the software ignores port data when determining flows. To enable per-flow
load balancing, you must set the
configuration.
To include port data in the flow determination, include the

If you include both the layer-3
Layer 3 and Layer 4 information to load-balance:
Source IP address
Destination IP address
Protocol
Source port number
Destination port number
Incoming interface index
IP type of service
The router recognizes packets in which all of these
identical, and ensures that these packets are sent out through the same interface. This
prevents problems that might otherwise occur with packets arriving at their destination
out of their original sequence.
This is appropriate behavior for Transmission Control Protocol (TCP) and User Datagram
Protocol (UDP) packets. For Internet Control Message Protocol (ICMP) packets, the field
location offset is the checksum field, which makes each ping packet a separate "flow."
There are other protocols that can be encapsulated in IP that may have a varying value
