Trying to set up some virtual interfaces for a network card.

So... eth0 = main card.
eth0:1 = 1st virtual
eth0:2 = 2nd virtual

Need to create a route from one, to the other.

I understand I need to create a /etc/sysconfig/network-scripts/route-eth file. But unsure if that is a route-eth0 file with the differences made out inside by doing

gateway1=xxxx
gateway2=xxxx

Or do I do an individual route-eth0:1 route-eth0:2 file and put the specific details in each as...

gateway0=xxxx

Solved it. Gave up trying to specify for a specific interface beyond the device.

So /etc/sysconfig/network-scripts/route-eth0

With

/ via

as a single line in the file. Makes all ips routable despite being on different subnets

original: 192.168.0.0/16
virtual: 192.169.0.0/16
gateway: 192.168.0.1

route line: 192.168.0.0/16 via 192.168.0.1

Sorted.
