	Hello,

	To all: do you have some working script(s) that we can
recommend for setups with 2 or 3 uplinks in multipath route? Then we
can link them to the web page as reference.

	Then can you explain what you learned from "2.4 Keeping them alive"
and what you have to keep the state for each GW from the multipath route
valid?

	This is strange:

> 172.16.0.0/24 dev eth0 scope link
> 10.10.10.0/24 dev eth2 scope link

	It means your settings are not created from script.
Also, the script does not bring dev eth0 up, there is a missing
"up".

	What do you have in table ADSL?

	Can you provide output from:

ip addr
ip rule
ip route list table all
