That's only part of the output.  You didn't, e.g., show the default
route.

Those are indeed redirects.  If you consult the netstat(8) man page:

     D       RTF_DYNAMIC     Created dynamically (by redirect)

This is usually because one of your routes is wrong, and the system it
points to is compensating by sending you redirects.
