Enhanced CPU core allocation for the Routing Engine

You can enhance system stability and performance by configuring an even number of CPU cores for the Routing Engine. When you launch instances with an even number of CPU cores configured, two CPU cores are allocated by default to the Routing Engine. This allocation enhances system stability and ensures the efficient operation of both the Routing Engine and Packet Forwarding Engine. For systems with an odd number of CPU cores, only one core is allocated to the Routing Engine. Use the [show security forward-options resource-manager] settings to verify the RE CPU core count. 

The [set security forward-options resource-manager cpu re <n>] command is now deprecated. You cannot manually configure the number of CPU cores on the Routing Engine because the default assignment automatically allocates these cores.
