Multipath Routing

[Michael W. Oliver]

[this was posted under another thread, so I am reposting as a new thread to 
hopefully generate some responses.  thanks.]

I am no programmer, so forgive my ignorance in that respect, but why can't a 
metric be used to differentiate routes to the same destination network 
within the routing table?  I happened to be googling and found:

http://daily.daemonnews.org/view_story.php3?story_id=3878

which describes a patch to -STABLE that does exactly what I am talking 
about.

Is there any reason why this shouldn't be implemented by default in the OS?  
I am not being critical of the FreeBSD operating system by any means, just 
curious.

Personally, I would very much like the ability of Zebra to feed the kernel 
the same route via multiple gateways, differentiating those routes by 
metric value.

Comments?
