Specify the source IP address used for probes. If the source IP address is not one of the router’s or switch’s assigned addresses, the packet uses the outgoing interface’s address as its source. Prior to Junos OS Evolved Release 23.1R1, only IPv4 addresses are supported for Junos OS Evolved.

The following addresses cannot be used for the source IP address used for probes:


  • (loopback)

  • (multicast)

  • (broadcast)

  • ::/128

  • ::1/128 (loopback)

  • fc00::/7 (unique-local)

  • 2001:db8::/32 (documentation prefix)

  • 2002::/16 (6to4)

  • 5f00::/8 (6bone)

  • 2001:10::/28 (ORCHID)
