Adding IP routes

How do I add routes to Fedora? I have a set of routes that I need to add but I'm not sure how to do that.

#ip route add help

Sample route add commands:

Code:

ip route add 172.16.16.0/16 via 172.16.16.1
ip route add 172.16.16.0/16 dev eth0
or
ip route add 172.16.16.0/16 via 172.16.16.1 dev eth0

I'm not a fedora expert but to make your route persistant after reboots I think you need to create files for each NIC in /etc/sysconfig/network-scripts,

For example,

Code:

bash-2.05$ cat /etc/sysconfig/network-scripts/route-eth0
172.16.16.0/16 via 172.16.16.1
bash-2.05$

There are two ways to this under FC5. The method specified above and this one, which in the ifup-routes script is called the "new" way. The old way is more concise; the "new" way puts something like this in the route-ethn file(s):

GATEWAY0=10.206.210.18
NETMASK0=255.255.0.0
ADDRESS0=10.210.0.0

Each route needs three entries, destination, mask, and gateway.

YMMV
