How to manually add route for vps.

As a network engineer, you probably spend a lot of time thinking and planning your network infrastructure.

You plan how computers will be linked, physically using specific cables but also logically using routing tables.

When your network plan is built, you will have to implement every single link that you theorized on paper.

In some cases, if you are using Linux computers, you may have to add some routes in order to link it to other networks in your company.

Adding routes on Linux is extremely simple and costless : you can use the Network Manager daemon (if you are running a recent distribution) or the ifconfig one.

[root@vps /]# ip route add 0.0.0.0/0 via 0.0.0.0 dev venet0
