Release Information

Statement introduced in Junos OS Release 17.3.

Description

Enable ECMP support for reverse traffic. In this case, Junos OS for SRX Series devices and vSRX instances use a hash algorithm to determine the interface to use for reverse traffic in a flow. This process is similar to asymmetric routing in which a packet traverses from a source to a destination in one path and takes a different path when it returns to the source.

If you do not enable this feature, the software selects a route in the ECMP set to the incoming interface for reverse traffic, which is the default behavior.
