  • Increased tunnel scaling (vSRX 3.0)—Starting in Junos OS Release 21.1R1, vSRX 3.0 is supported by a new architecture similar to SRX5000 line of devices with SPC3 which increases the tunnel scale.

    vSRX 3.0 instances support the IPsec VPN features that are supported on the SRX5000 line of devices with SPC3 (SRX5K-SPC3).

    By default, when the vSRX 3.0 boots up, the legacy architecture is executed. To enable the new architecture, you must load and install a new package, junos-ike. The Junos OS releases includes this package, but its installation is optional. As an administrator, you must execute the request system software add optional://junos-ike.tgz command to load the junos-ike package.
