routing (System Processes)


Hierarchy Level


Configure routing protocols process (rpd) mode.


force-32-bit mode is used in Junos 15.1F2 and prior releases

auto-64-bit mode is used starting in Junos 15.1F3



(Optional) Enable to use 64-bit mode. If the system is 64-bit capable and has at least 16 GB of RAM, then auto-64-bit will cause the Routing Engine to run in 64-bit mode. Otherwise, it will run in 32-bit mode.


This option is not applicable for logical systems.

Starting in Junos 15.1F3, 15.1R2, 15.1R3, and 15.2R1, 64-bit mode is enabled by default on systems that support it and which have at least 16 GB of RAM.


(Optional) Enable to always use 32-bit mode.


For MX Series routers, virtual private LAN service (VPLS) dynamic profiles are not supported with the 64-bit mode routing protocol process (rpd). To enable VPLS dynamic profiles configuration, configure the routing process to use 32-bit mode.


(Optional) Enable to always use 64-bit mode.


You need not restart the routing protocol process (rpd) to use the 64-bit mode. However, forcing rpd from 32-bit to 64-bit or 64-bit-to 32-bit will restart the rpd process, which can impact the routing protocols. For this reason, it is recommended to perform these changes in a maintenance window.
