Description
It is possible to set alternative fib for listening sockets via "setfib" option in "listen" directives.
It would be convenient to have similar functionality for outgoing connections in ngx_http_proxy_module and ngx_stream_proxy_module.

I'm about to implement this per-socket FIB selection on FreeBSD for upstream connections and for stream and, possibly, mail listening sockets.
For upstream connections I'm going to add proxy_socket_setfib directive.
Example config snippet:
location /proxy-site/ {
proxy_pass http://...;
proxy_socket_setfib 2;
}
Possible SETFIB values are non-negative numbers, incl. 0, less than 16 (on current FreeBSD versions)
But I'm not sure how to represent default value for this directive. The default value designates no SETFIB socket option is applied, default fib for the process is used.
There are two variants:
Syntax: proxy_socket_setfib number;
Default: proxy_socket_setfib -1;
Syntax: proxy_socket_setfib default | number;
Default: proxy_socket_setfib default;
First one with -1 is simpler, but -1 is not usual default value for nginx directives, moreover it's equal to NGX_CONF_UNSET
