Become superuser on the machine to be configured as a router and do the following:
For example, create hostname.ie0 and hostname.ie1. (See "/etc/hostname.interface File" for more information.)
Type in each file the host name you have selected for that interface.
For example, you could type the name timbuktu in the file hostname.ie0, then type the name timbuktu-201 in the file hostname.ie1. Both interfaces would be located on the same machine.
184.108.40.206 timbuktu #interface for network 192.9.200 220.127.116.11 timbuktu-201 #interface for network 192.9.201 18.104.22.168 gobi 22.214.171.124 mojave 126.96.36.199 saltlake 188.8.131.52 chilean
The interfaces timbuktu and timbuktu-201 are on the same machine. Notice that the network address for timbuktu-201 is different from that of timbuktu. That is because the medium for network 192.9.201 is connected to the timbuktu-201 network interface while the media for network 192.9.200 is connected to the timbuktu interface.
