Routed's radix code is unable to handle > multipath routes. maybe i am confused. but my momma told me that routing != forwarding. i.e. routed will receive two default routes and i hope would install them in the fib, where RADIX_MPATH forwarding would take over. am i wrong about what routed will do? will it choose only one to install in the fib? randy
