@@ -1653,12 +1653,16 @@ are translated to appropriate system (and OS-specific) route attributes.
We support these attributes:
<descrip>
<tag>int <cf/krt_source/</tag> The source of the imported
<tag>int <cf/krt_source/</tag> The original source of the imported
kernel route. The value is system-dependent. On Linux, it is
a value of the protocol field of the route. See
/etc/iproute2/rt_protos for common values. On BSD, it is
based on STATIC and PROTOx flags. The attribute is read-only.
<tag>int <cf/krt_metric/</tag> The kernel metric of
the route. When multiple same routes are in a kernel routing
table, the Linux kernel chooses one with lower metric.
<tag>ip <cf/krt_prefsrc/</tag> (Linux) The preferred source address.
Used in source address selection for outgoing packets. Have to
be one of IP addresses of the router.
