Static Route on IOS CISCO

OS: IOS

To create static route to loopback interface for this network.

First assign ip address for each interface FastEthernet0/0 and Loopback0 at each router.

router1(config)#interface FastEthernet0/0

router1(config-if)#ip address 192.168.0.1 255.255.255.252

router1(config)#interface Loopback0

router1(config-if)#ip address 172.16.0.1 255.255.255.255

router2(config)#interface FastEthernet0/0

router2(config-if)#ip address 192.168.0.2 255.255.255.252

router2(config)#interface Loopback0

router2(config-if)#ip address 172.16.0.2 255.255.255.255

To get access to Loopback0 at router2 from router1, you need to add static route at router1.

router1(config)#ip route 172.16.0.2 255.255.255.255 192.168.0.2

Test it with ping

router1#ping 172.16.0.2

For router2 to get access to Loopback0 at router1, add static route at router2.

router2(config)#ip route 172.16.0.1 255.255.255.255 192.168.0.1

Test ping again

router2#ping 172.16.0.1

Hostname on JUNOS Juniper

OS: JUNOS 8.5R1.14

To configure hostname for JUNOS

#set system host-name router1

Don't forget to commit

#commit

Check it with

#show system host-name

Change Network Device Name on CentOS

OS: CentOS 6.3

Sometimes when you make clone of a virtual machine via KVM or VMWare, network device name are automatically change from eth0 to eth1.

To show your current device name use:

#ip link show

As you can see right now mac address 00:0C:29:5E:61:F2 are set to eth1.
To change it back to eth0 use:

#ip link set eth1 name eth0

To make sure the device name did not change back to eth1 after restart, edit:

/etc/udev/rules.d/70-persistent-net.rules

You could delete the old mac address and edit the device name from eth1 to eth0

Don't forget to modify mac address at the network configuration:

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

Make sure mac address already set to new one

Turn on eth0, and check it:

#ifconfig eth0 up
#ifconfig
