alternative routing - deadlock?

[D]

on freebsd box such a simple situation(see below) seems to be pretty complicated:


ISP1[10.10.10.1][1Mbps]<-------------------->[ME-em0][10.10.10.10]
ISP2[11.11.11.1][8Mbps]---------------------->[ME-em1][11.11.11.11]
default route 10.10.10.1

any traffic "from ME to ISP2" will fail or will be redirected via ISP1.

alternative routing function should allow us to add another static route:
default route 11.11.11.1

as far as i know, linux machines allready have this feature.

so, is it possible to solve this problem with any means for today?

ps: some rudiments can be seen in here:
