Learn about changes in behavior of vSRX features and changes in the syntax of Junos OS statements and commands in Junos OS Release 20.1R1 for vSRX and vSRX 3.0.

Flow-Based and Packet-Based Processing

  • Equal-cost multipath (ECMP) is used to load-balance traffic by using equal cost routes. However, enabling ECMP on SRX Series devices and vSRX instances does not result in load balancing when the next hops are reachable through different nodes in a chassis cluster. Use the set security flow no-local-favor-ecmp command to allow route selection on both the nodes. After you run this command, load balancing will work even if the outgoing interfaces are active on different nodes. For more information, refer to KB article KB35365
