NodeGHO-Configs

These are the configurations for the Linksys WRT54GS that is acting as Node GHO's router.

The Firmware is OpenWRT, precompiled squashfs snapshot from the OpenWRT website dated 25 May 2005.

Once the firmware had loaded the NVRAM was cleared and set to defaults using the mtd erase nvram && reboot command. This gets rid of any NVRAM variables that aren't used by OpenWRT. The filesystem was then reset using the firstboot command.

The WRT54GS has been set up so that each port on the switch is a separately routeable network interface. Each port has it's own IP address and it's own subnet, separate from the other ports. This is achieved with the vlanNports=X Y... and vlanNhwname=et0 variables.

It is running Quagga/OSPF version 0.98.1
