Well, something like this can probably be used:

~RTF_GATEWAY   maps to local     (2),  -- local interface
RTF_STATIC     maps to    netmgmt   (3),  -- static route
RTF_DYNAMIC    maps to    icmp      (4),  -- result of ICMP Redirect

other routes?         other     (1),  -- not specified

RTF_PROTO1     tells us thet it is dynamic route, and you have to use 
quagga/bird/openbgpd/whatever cli / api to get more precise results.

You can examine `netstat -rn -finet` output with netstat(8) to get good 
overview for common route types.
