This is the correct answer because Layer 4 distribution is not recommended when dynamic routing protocols are used in Maestro. Layer 4 distribution is a feature that adds the source and/or destination ports to the distribution equation, which can improve the load balancing among the SGMs. However, it can also cause issues with the correction layer, which is a mechanism that ensures the packets are processed by the correct SGM. Dynamic routing protocols, such as BGP or OSPF, use specific ports to exchange routing information and establish neighbor relationships. If Layer 4 distribution is enabled, it can interfere with the routing protocol packets and cause routing instability or failures.

The asg calc command is a tool to show which SGM is selected to receive traffic based on the distribution mode and the packet parameters. It takes the port number, the source IP, the destination IP, and optionally the source port and the destination port as arguments and returns the SGM ID and the hash value. For example, asg calc 1 10.0.0.1 20.0.0.2 1234 80 will show which SGM will receive the traffic from 10.0.0.1:1234 to 20.0.0.2:80 on port 1.

Maestro allows you to define the distribution mode per interface, which determines how traffic is distributed among the Security Group Modules (SGMs) in a Security Group. You can configure the distribution mode for each interface individually, or use the default mode for all interfaces. The distribution mode can be set for both uplink and downlink interfaces.

Check Point reduced throughput degradation to 1% per added SGMs. For example, the overall throughput degradation is 10% for 10 SGMs in a Security Group. Check Point aims to reduce this even further in the future. https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk147853
