Debian / Ubuntu Linux static routing for two interfaces:
Here is a config file named /etc/network/interfaces:
auto lo
iface lo inet loopback auto eth0
iface eth0 inet static
address 10.9.38.76
netmask 255.255.255.240
network 10.9.38.64
broadcast 10.9.38.79
### static routing for eth0 that connects to the VLAN ###
post-up route add -net 10.0.0.0 netmask 255.0.0.0 gw 10.9.38.65
pre-down route del -net 10.0.0.0 netmask 255.0.0.0 gw 10.9.38.65 auto eth1
iface eth1 inet static
address 204.186.149.140
netmask 255.255.255.240
network 204.186.149.128
broadcast 204.186.149.143
## default gateway for eth1 and the server ##
gateway 204.186.149.129
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 10.0.80.11 10.0.80.12

ip command to set a default router to 192.168.1.254
# ip route add default via 192.168.1.254
route command to set a default router to 192.168.1.254
route add default gw 192.168.1.254
Save routing information to a configuration file /etc/network/interfaces
Open /etc/network/interfaces file
# vi /etc/network/interfaces
Find eth0 or desired network interface and add following option
gateway 192.168.1.254
Save and close the file. Restart networking:
# /etc/init.d/networking restart
A note about ip command and persistence static routing on a Debian/Ubuntu
Edit your /etc/network/interfaces file for say eth0:
# vi /etc/network/interfaces
Update it as follows:
auto eth0
iface eth0 inet static
address 192.168.1.2
netmask 255.255.255.0
gateway 192.168.1.254
## static ip config START ##
up /sbin/ip route add 172.10.1.0/24 via 10.8.0.1 dev eth0
down /sbin/ip route delete 172.10.1.0/24 via 10.8.0.1 dev eth0
## static ip config END ##
Restart networking service when using a Debian or Ubuntu Linux
# systemctl restart networking
