Static Route on IOS CISCO


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
router1(config)#interface Loopback0
router1(config-if)#ip address

router2(config)#interface FastEthernet0/0
router2(config-if)#ip address
router2(config)#interface Loopback0
router2(config-if)#ip address

To get access to Loopback0 at router2 from router1, you need to add static route at router1.
router1(config)#ip route
Test it with ping

For router2 to get access to Loopback0 at router1, add static route at router2.
router2(config)#ip route
Test ping again

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:
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:
Make sure mac address already set to new one

Turn on eth0, and check it:
#ifconfig eth0 up
