- Contains lines that are arguments to "/sbin/ip route add"
- For example:
+ Contains lines that specify additional routes that should be added when the
+ associated interface is brought up.
+
+ The files are processed by the ifup-routes script and uses the /sbin/ipcalc
+ utility for all network masks and numbers. Routes are specified using the
+ syntax:
+
+ ADDRESSn=<network>
+ NETMASKn=<network/prefix mask>
+ GATEWAYn=<next-hop router/gateway IP address>
+
+ The "n" can be any integer number, but is expected to be monotonically
+ increasing and counting starts from 0. For example:
+
+ ADDRESS0=192.168.2.0
+ NETMASK0=255.255.255.0
+ GATEWAY0=192.168.1.1
+
+ adds a network route to the 192.168.2.0 network via the gateway at
+ 192.168.1.1. Since you must already have a route to the network of the
+ gateway, there is no need to specify a device.
+
+ Note: The ifup-routes script also supports an older syntax designed to be
+ used directly as an argument to "/sbin/ip route add". This syntax is
+ deprecated, but if no "ADDRESSn" lines are found the following will still
+ work:
