I wrote it works for me.

It does.

(spam-protected):~# ip route add 192.168.6.6 via 192.168.7.7 dev lo src 172.31.11.11
RTNETLINK answers: Network is unreachable
(spam-protected):~# ip route add 192.168.6.6 via 192.168.7.7 dev lo src 172.31.11.11 onlink
(spam-protected):~# ip route show 192.168.6.6
192.168.6.6 via 192.168.7.7 dev lo src 172.31.157.11 onlink 
(spam-protected):~#

172.31.11.11 is MainIP and is configured on another interface.

For next hop IP address that does not meet kernel checks. E.g. neighbor is on other subnet.

Is your main address configured?
