</div>Manual setup:<br>
<br>
[root@lin2 ~]# route add default gw 217.20.117.1 dev eth0<br>
[root@lin2 ~]# route add host 217.20.117.1 netmask 255.255.255.255 dev eth0<br>
<br>
Automagical setup:<br>
<br>
[root@lin2 ~]# cat >>/etc/sysconfig/network-scripts/route-eth0<br>
ADDRESS0=217.20.117.1<br>
NETMASK0=255.255.255.255<br>
EOF<br>
[root@lin2 ~]# cat >>/etc/sysconfig/network <<EOF<br>
GATEWAY=217.20.117.1<br>
EOF<br>
<br>
The *assumes* that the network (switch or router box) that eth0 is<br>
connected to also has 217.20.117.1 connected to it. Typically a router<br>
'box' contains both the router and a ethernet switch: a 'pure' router<br>
would only have two ethernet jacks, one for each of the two networks the<br>
router routes between. Since there is no great demand to put a single<br>
machine on a network and since the switch hardware is dirt cheap and<br>
since no one does coax Ethernet anymore, modern router boxes include a<br>
switch in the 'inside' network.<br>
