Release Information
Command introduced before Junos OS Release 7.4.
Starting in Junos OS Release 22.1, we support RA proxy on SRX Series and vSRX 3.0 . This command output is modified to display the configured upstream interfaces, downstream interfaces, the proxy flag, the proxy blackout timer, and the passive mode information.
