1, first set the IP address for eth0 and eth1 under B computer

Open configuration file

#vim/etc/sysconfig/network-scripts/ifcfg-eth0

Device= The name of the NIC

Bootproto= whether to use DHCP, choose not to use in the experiment

Hwaddr= whether to add a network card number (MAC)

Ipaddr= is the IP address .

netmask= Mask

network= domain, which is the network segment you are in

onboot= here to select Enable, i.e. YES

gateway= Gateway

broadcast= broadcast address, in the experiment without the tube

After the configuration is complete, restart the network service

#service Network Restart

the network card configuration method of several other computers and B Computer, just configure the eth0 after the configuration eth1 on the selection .

2. Configure static routing table

File path:

C Computer routing table configuration

3 . Check if the routing forwarding feature is enabled

[Email protected] ~]# Cat/proc/sys/net/ipv4/ip_forward

1(if 1 is shown here ,indicates enabled, if 0 is displayed, it is not enabled)

If not enabled, use this command to enable:

#ech0 1 >/proc/sys/net/ipv4/ip_forward

C Computer also to enable routing forwarding

4. Change The routing configuration file. (Because the routing settings configured by the previous command are lost after the network service is restarted, change the configuration file)

#vim/etc/sysctl.conf

650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M02/45/E1/wKioL1Ps1OSTStjtAAHBmpqaP4I932.jpg "title=" 4.png " alt= "Wkiol1ps1oststjtaahbmpqap4i932.jpg"/>

Use after configuration is complete

#sysctl –p

Make the configuration file effective immediately

Then restart the Network service

C Computer also to change the routing configuration file

After the above configuration is completed, the static route under Linux even if the configuration is complete, I'll look at the results.

At this point, static routing is complete, rookie experiment notes, the shortcomings of the great God, please teach,
