Ah!  I obviously didn't pay close enough attention to the
documentation.  I'll give this a shot.

So, should I be able to do something like this (I'll test later):

ip route add default via aaa.bbb.ccc.ddd dev eth1 table 100
ip route add default via bbb.ccc.ddd.eee dev eth2 table 100

And eth1 will be used until failure?

Makes sense, and it's not necessary with your alternative routes
implementation.  I'll re-read the docs. :)

Thanks for the help.

BTW, any idea whether your patches are going to make it into 2.4
proper?
