No, there is no load-balancing....
It is a server on the LAN with two NICs, two IPs and I want to access 
the internet on both interfaces ... which means, practically, different 
WAN connection, but from the server's point of view doesn't matter, the 
routing to different WAN is a job of gateway's.
And as I said in the initial message I achieved this ... :)
The question is how can I achieve this with more elegant way, because 
the "route" command is deprecated anyway.

So, again:
Centos 7
2 NICs
default gateway on enp2s0 is, defined in /etc/sysconfig/network

Which other way (preferred with "ip route") can I add this, but:
#route add default gw dev enp3s0
