Ok, let's try it like this then:

ifdown --force eth1
ip l s dev eth1 down
ip a d dev eth1 192.168.2.8/24
ip a d dev eth1 2001:8b0:ff60:6a91::8
ifup -v eth1

First, if you're configuring eth1, what's the point of setting the
route via eth0.
Second, if you're configuring ipv6 route, you should use 'ip -6'
instead of straight 'ip'.
And third, using default link-local ipv6 address as a gateway is kind
of weird. Although if ipv6 /128 address mask works for you - who am I
to argue.

This seems to be the current source of trouble. I wonder what
