Description

Enable VPN session affinity. In session affinity feature, we’ve optimized tunnel redistribution. After tunnel redistribution, the data path might not be optimal, hence we recommend that you enable VPN session affinity to ensure that the data path is optimized. During optimization, the current data path experiences a higher packet delay until it is fully optimized.

This feature is supported on SRX5400, SRX5600, and SRX5800 devices. By default, VPN session affinity is disabled.
